.do file


What is a .DO file

The DO file extension references a Java Servlet. It is a Web-based Java application executed by a Web server like the IBM WebSphere.

This .do file format is usually mapped to the Struts controller. And it is utilized for the generation of dynamic Web contents.

  • A servlet is a language class of Java for extending the functionalities of servers hosting programs. It is accessible through a request-response infrastructure model.
  • This API supported by .do files provides with the ability of creating dynamic Web pages on a server running on the Java platform.
  • Normally, the dynamic contents are based on the HTML scripting language but can also be from other models like the XML.
  • Servlets are widely considered as the counterparts of the dynamic contents generated by the ASP.NET, CGI, and PHP technologies.
  • The functionality of this do file extension supports the maintenance of state across various server transactions via HTTP cookies, URL rewriting, or session variables.

How to Open DO Files

These are the programs that you can use to view these do files. The web browser can be used to view a do file.

Open With Windows: Requires a Web server that supports JSP to run, may be viewed in a Web browser:

  • Google Chrome
  • Internet explorer
  • Mozilla Firefox
  • Opera
  • Safari
  • Apache Tomcat
  • Any other web browser
apache tomcat
Open With Linux: JSP-supported Web browser, may be viewed in a Web browser:
The Java package containing the servlet API identifies the interactions that can occur between the servlet and the Web container.
Basically, the Web container is a component of the Web server. It is the responsible for the management of the lifecycle attributed to the servlets.
It also maps a URL to a specific servlet and makes sure that that URL requester has the appropriate access privileges to communicate with its target.
Servlets supported by the DO file format can be generated by the JSP (JavaServer Pages) compiler. Also by template engines like the WebMacro.
Servlets executed in combination with the JSP are normally referred to as Model 2 patterns.
They are considered as a variant of the model-view-controller outline.
The lifecycle of this do format in relation to the servlet consists mainly of its loading at startup by the container using the init() method.
Upon completion of the initialization, it begins servicing the client requests using the service() method.
The destroy() method is executed in the final stage to terminate the servlet service.

File type: Drawing Exchange Format


What is

The DXF file extension is used in Autodesk applications for Drawing Interchange Format or Drawing Exchange Format files. This data file format for CAD files was created by Autodesk for the purpose of allowing data interoperability among Autodesk software and other applications.

It was initially launched as a component of the AutoCAD 1.0 in December 1982. The release had the intention to provide the same and exact data representation of an AutoCAD drawing with the .dwg file extension, which is its local file format.

The files with the .dxf file extension are vector image files and are the data format designed by Autodesk used in computer-aided design.

It is similar to the DWG  but it has more compatibility with other programs because it is cased in ASCII. AutoCAD versions from Version 10 and later support binary and ASCII forms of files with the .dxf file extension. Early versions of AutoCAD only support ASCII.

Category: Settings file, Developer files
File format: Proprietary
Open with Windows: IMSI TurboCAD, Autodesk AutoCAD or DWG TrueView, SolidWorks eDrawings Viewer, ACD Systems Canvas, DWG converter such as AutoDWG, IrfanView
Open with Linux: TurboCAD, Autodesk AutoCAD
As the AutoCAD software was developed to have more powerful features and tovsupport objects of the more complex type, the DXF file format became less used. Some object types such as ACIS regions and solids cannot be documented.
Because of this, various CAD applications utilize only the DWG file format licensed by Autodesk or can be supported non-natively by Open Design Alliance.

File type: Mac OS X Disk Image


Open DMG File

The usage of the DMG file extension is in the context of a mountable disk image file which is generated by the Mac OS X Operating System platform. Once the file is opened, the system will mount it in a virtual disk located on the user's desktop.

This type of file is normally utilized for the distribution of software installation packages for the Macintosh computer system.

Prior to the introduction of this file format, the Mac environment utilized the IMG up until the introduction of the Mac OS 9. The Apple Disk Utility is the main application associated by users to this particular file type under the Macintosh platform and is bundled with the Mac OS X installation package.

Although not meant to be directly opened under the Microsoft Windows Operating System platform, the DMG format file can be accessed by Windows users by using some third party applications in the market. Basically, the DMG file extension can be compared to the EXE or ISO format of Windows and can even function as a complete virtual drive for the system.

The mimicking of physical CD drives is a workaround implemented by the system to address problems that may arise from CD requirements of some software programs including support for the efficient usage of an organization's resources.

Category: Disk Files
File format: Proprietary
Open with Windows: Acute Systems TransMac, DMG2IMG or DMG2ISO
Open with Linux: N/A
The DMG format file is also used by video games distributed for the Macintosh computer environment which are commonly protection enabled.
This format makes sure that all software installation and execution in the system are carried out correctly by providing support for both physical and virtual drives required by the system.
Running an application from a virtual drive may also allow a user to execute a program without actually copying an instance of it in the physical storage drive of the computer system.
This will save storage space and proves to be advantageous especially for programs which are not used very often. Aside from the Apple tool bundled with the Operating System, other more commonly used utilities that serve as an alternative include MagicISO, IsoBuster, and UltraISO.
These programs are more popularly executed under the Windows environment but are capable of reading DMG file formats and compressing them into another file extension that is more popularly used.
Another example of this conversion program is the DMG2ISO.

File type: Borland Paradox database


What is

In general, the DB file extension references a generic database file used for the storage of various types of information using a structured format.

This file with .db extension may be generated by a number of varying database applications or can be imported into different database software.

More specifically, the .db  format is the default used by the Borland Paradox database. This program is considered as an RDBMS (Relational Database Management System) that was originally developed by Borland until it was acquired by Corel Corporation.

This is perhaps one of the oldest commercially available database applications in the market having been launched during the DOS era by the Ansa Software in 1985.

Borland officially released the Windows-based version of this application in 1992. The DB file extension supported the highly successful database application which was subsequently retooled under the Borland C++ windowing toolkit and eventually utilized a different extended memory access scheme.

This program was distinguished from the xBase clones of dBase by its visual Query By Example functionality which was supported by its AI engine.

Oracle database also creates files with .db extension.

The DB file supported Paradox for Windows was an entirely different software altogether developed by a new team of programmers.
Even if majority of the feature sets inherent under the DOS environment were retained, a major difference lied on the compatibility with PAL to ObjectPAL including its shift to the GUI (Graphical User Interface) design for the Forms and Reports feature.
The use of PAL, although controversial, was forced primarily due to the lack of acceptable equivalent for the keystroke recording operation in Windows.
The DB file extension supported the object-based programming language founded on the Hypercard ideas as replacement for the keystroke recording.
The application also capitalized on the functionality of the right button of the mouse pointing device.
By using the right-click feature under the Forms and Reports window, the Properties is displayed.
This functionality is based on the implementation of Xerox Alto and Smalltalk which are now a standard for all Windows-based applications.
Historically, the DB file extension supported Paradox competed for market share with dBASE until both companies were eventually acquired by different corporations.


File type: Microsoft Word Open XML Document


What is a DOCX File?

DOCX files were first used by Microsoft in the 2007 Microsoft Word program. It is a "Microsoft Word Open XML Format Document".

The Open XML standard used by the new document file version of Office Word was intended to represent word processing files, presentations, charts, and spreadsheets. The Office Open XML file format specification became an open and free standard in 2006. Microsoft implemented its version as a successor to the earlier binaries of its applications and to the Office 2003 XML format files.

What makes DOCX really special is that you can use it for a variety of projects. These include; newsletters, flyers, resumes, reports, documentation and cover letters.

DOCX files do not only comprise of text, but they may also consist of a variety of objects, images, formats and styles. Another thing that makes DOCX files better than traditional DOC files is that they are much smaller in size.

They are also more compatible than DOC files.


To open a DOCX file using Microsoft Word, you need to use the 2007 version or higher. As mentioned earlier, you can make use of the Word Viewer to open DOCX files even if Microsoft Office is not installed on your PC system.


DOCX files can be opened and edited using any of;

  • OpenOffice Writer and
  • Kingsoft Writer.

Web-based Programs for opening and editing DOCX files


#1: Google Docs

 You can also use Google Docs to open and edit DOCX files. The good thing is you do not need to download Google Docs as it is an online program. You only need to upload the DOCX file to your personal Google Drive account. This has to be done before you can use Google Doc to open and then edit the DOCX file.


#2: Microsoft Word Online

 You can use Microsoft Word Online to open as well as edit a DOCX file when you are online. Microsoft offers this service and the overall appearance of the interface is similar to the standard Microsoft Word on a Windows OS PC. This Microsoft online service is also absolutely Free.


#3: Chrome Browser Extension

 Another way to view and edit DOCX files is to use a Chrome browser extension by Google. This is also a free web-based program for opening and editing DOCX files. You can open them straight on your Chrome browser. What's more, you would not need to first download the DOCX file before you can view it on the Chrome browser. This helps if you want to first check the DOCX file before downloading it to your hard drive.


In Conclusion


DOC and DOCX files have come to stay. They make it easy for you to share large documents in a variety of formats including PDF format.

By having large files compressed in a ZIP file, these documents can be sent via email to a number of recipients. Having any of the programs in this article would help you in opening and editing DOC files.

If you are on the internet, then you can use the free Chrome browser extension, Microsoft Word Online or Google Docs to access your DOC files.

  • Beginning with the Microsoft Office 2007,
the ECMA-376 (OOXML format) became the default format for all Office Word document files. Microsoft Office 14 would be the first commercially available productivity suite to employ the ISO/IEC IS 29500 specification compliant edition of the Office Open XML.
Before the market launch of the Microsoft Office 2007 suite, the central applications incorporated in the productivity package included Word, PowerPoint, and Excel.
These applications, by default, saved data in binary files which lacked interoperability functionality making them difficult to access from other applications in the same category.
The problem arose from the absence of a publicly available royalty-free data which would allow access to the specifications of file formats.

File type: Microsoft Word Document


The DOC file extension in computing terms is an abbreviation for a document file. It is normally created by a word processing application. And serves as the default format of the Microsoft Word program.
This application is a component of the Microsoft Office Productivity Suite that can incorporate print settings, page formatting, charts, graphs, tables, images, and formatted text among others.
Historically, the use of the .DOC extension only referenced plain-text file formats generated by a wide array of Operating Systems.
By the 1980s, the WordPerfect application made this the default extension of their proprietary format. At the time it was the most dominant word processing application in the computer market. WordPerfect continued to exert its dominance over the word processing industry until Microsoft wrestled the title sometime in the 1990s.
From the start, Microsoft Word has utilized this file extension as its standard for its generated files.
Binary formats usually store more text formatting data compared to other document file standards like RTF (Rich Text Format) and HTML (HyperText Markup Language) which are also less compatible with other word processing programs.

dat file

  • File type: Generic Data
  • Extension: .DAT
  • Format: open source


What is a DAT file

The DAT file extension is a generic data format. A number of distinct applications generate it. Usually the same program that created it.

This file can store information in either binary or text format with the text-based data file. You can view it with any standard text editing program. The structure of this file type is not from any specific outline due to its broad range of uses.

The exclusivity about this format is primarily in the area of allowing its access to the specific files it is associated with. Any attempt to open this file by any other application would result in an access error.

Moreover, this file type is virtually useless without the application it is identified with. The best and easiest way to identify the application is to contact its author.

The use of trial and error method is completely out of the question. Due to the wide usage of this particular type in the computer industry.


How to Open DAT Files

Problems opening .DAT files

These files should be opened in the application that created them. So finding out which computer program made the one you intend opening is important.

Note that not all DAT files can be extracted and modified using basic computer programs. For example, those DAT files for your Mac or Windows computer systems that are used for storing language codecs.


On your Windows and Mac OS


  • Step#1: Find out which Windows OS computer program made it.

Before you can open that DAT file on your Windows PC, you need to know which program is responsible for creating it.

  • Step#2: Launch the program.

Simply click the program once or double-click the program icon in order to launch it.

  • Step#3: Click on "File" drop-down menu.

The "File" drop-down menu can be located at the top left hand side of the application's window.

  • Step#4: Click on "Open".

From the "File" drop-down menu, click on the "Open" option. This should launch a "File Explorer" window.


For Mac PC


In the case of your Mac PC, drag your selected DAT file and drop it in the application's window. Note that with your Mac PC, the selected will not be viewed as a readable file.

So you would not be able to open your selected DAT file by simply going to the "File" menu of the program and clicking "Open", as it is the case with a Windows PC.


  • Reveal "All Files" on "File Explorer".

To reveal every files on "File Explorer" and that includes the DAT file you want to open, you should click on the box labelled "file type". This can be seen on the right side of the text field titled "Name". A drop-down menu will then emerge and you simply have to click on the "All Files" option.


  • Click to select it.

Locate the DAT file you want to open and to select the file, just click on it once.


  • Click on "Open".

The "Open" option can be seen at the bottom right hand side of the program's window. Clicking this option will lead to the opening of your selected.


  • Check to see if the DAT file can be viewed.

You need confirmation that your selected DAT file can be viewed. There are instances where an alert notification pops up, suggesting that the contents of your selected one are not compatible with the DAT file extension.

If this occurs, just click on the "Yes" or "Open" option in order to open your selected DAT file.


  • Have the extension of the selected DAT file changed.

You can save yourself the stress of constantly needing to drag a selected DAT file to their respective programs in order to get them opened.

All you need to do is to have the extension changed. Nevertheless, keep note of the precise extension for the DAT file to avoid file breaking.


For Mac

 Your DAT file should be selected.

  1. Click on the "File" drop-down menu and then click on "Get Info".
  2. You will see a triangle shaped object beside the category titled "Name & Extension", click on this triangle shaped object.
  3. A "Hide Extension" check-box would be seen, you can uncheck this box.
  4. Change the DAT extension using the new name of your selected file's extension.
  5. Click "Return" first followed by "Use . extension" once it pops up.


One of the more popular variants of the DAT file extension is the INDEX.DAT. Which is associated with the shield attributes that focus on storing details. It is about the allowed websites visited by the user as well as saving information on his surfing history.
It is normally stored with hidden properties in the same folder or directory as its application.
The DAT files extension has relation with video streams using the MPEG  formats. In this context, the DAT format usually contains information on the type of video contained. Its name, and its length.
This data is in binary form. And it is not readable even if the files can be opened with a standard text editor.
This generic data format is an integral part of some applications. They may not function properly without its presence.


File type: Mozilla Partially Downloaded Files


The DOWNLOAD represents a partially downloaded file by the Download Manager component of the Mozilla Firefox Web browser program.
This files represent that it is either currently being actively downloaded or awaiting for additional download resource to completely retrieve the target file.
This may also signify files which the user has intentionally stopped the downloading process for one reason or another.
The downloading of the files with the DOWNLOAD file extension can be resumed by the user once an active Internet connection under the same Web browser initiated the downloading.
This file extension is normally replaced with the appropriated format once the downloading process  has been successfully completed.
Under the Mozilla Firefox Web browser, the user has the option of pausing, cancelling, and resuming the download process along with the functionality of specifying the exact location where the downloaded file should be stored by the application.
Currently, there are duplications of coding that relate to the path name and files validation process used by the browser and its external helper application service caused by the lack of an overall simplified API to cover the file transfer coalescing process.

How to Open Download Files

Category: Web Files
File format: Proprietary
Open with Windows: Mozilla Firefox , Safari
Open with Linux: Mozilla Firefox , Safari
  1. Find your file
  2. Double click on it
  3. If it is not opened by default. Select the program: mozilla firefox or Safari
  4. Click on it
There are instances where in the download process becomes sluggish. This is probably caused by the DOWNLOAD file extension having a long downloads history.
Essentially, when a paused download process receives a resume instruction, the application initially verifies the downloads history to check on the status of the download file. Then, identify the point where the process was stopped, and the sites involved in the downloading process.
The DOWNLOAD file extension normally does not support Torrents.
The Download Manager component of Mozilla Firefox has also undergone significant changes with the introduction of the Firefox 3. It supports the development of decreasing the efforts involved in the use of it. Including the improvement of the interaction between the user and the software.
It supports two essential processes involved in the file downloading operation:
  • Controlling and watching the download progress,
  • And locating files that the user has downloaded in the past.

File Extension type: Dynamic link library


What is a .DLL file extension format

This format also know as Dynamic Link Library is a file shared between a number of software programs (and are similar to .EXE files). It is used in Microsoft Windows and OS/2 operating systems.

These files will contain compiled procedures, or drivers (for example for a printer) which a range of programs can then all access. You will often come across DLL files in the context of not having them, which is to say if you plug a new piece of hardware into your PC the computer might complain about missing the 123XYZ.DLL.

In practice this means that the system cant find the driver associated with this hardware. You will usually be able to download legitimate DLL files from a CD accompanying the hardware, or off the Internet from the hardware producers website. 

Additional comments: It is unlikely that you should ever have to open or edit a file extension dll (unless you are a specialist). Also note that these can be a source of infection and should be saved from the Internet or executed from an email, with care.

Appropriate program for file extension DLL
