Dfont Format

Dfont stands for data fork TrueType and it is a special form of TrueType font format. The file is specifically for Macs operating systems that are running Mac OS X. Some of the system fonts that come preinstalled on OS X come as dfont fonts. This type of file format will not be on a different operating system. TrueType is a very popular font format on Linux, Windows and Macs computers. It looks very good on the screen and equally offers great quality in its output.

History

The TrueType font had been around for a very long time. It had been in use since the early parts of the 1990s. However, it is getting gradually replaced by the OpenType font format, which is more recent and features more functionality. The file can also be used on various versions of the Windows Operating System. Like the Windows XP, Windows Vista, Windows 8/8.1, Windows 7 and Windows 10.

Every end-user can easily access the active system fonts. The system fonts must be saved in the /Library/Fonts/ folder. The active user fonts, on the other hand, can only be accessible to the current end-user. And you must save it in the /users/username/Library/Fonts/ folder.

In the earlier versions of the Mac operating systems, like System 9, one could store data in two different entities, which are:

• Resource fork
• Data fork

The mechanism was equally sued for TrueType fonts in which all pieces of information related to the fonts was in the resource fork. When developing OS X, Apple decides to change its method of data storage from the forks concept. As a result, files only have a data part. As a result, the old System 9 TrueType fonts became obsolete and inapplicable in the regular data section of OS X files. Consequently, we end up with the data fork TrueType fonts or dfonts fonts.

You should not take anyone seriously that asks you to avoid the use of Dfont fonts in the professional publishing environments. This is because the quality of the Dfont fonts is similar to that of any other TrueType font. The only channeling is that the fonts are not compatible across different platforms.

File type: dBASE Database Backup File

File Extension DBK

The DBK file extension supports the backup functionality of the dBASE RDBMS software. This file format represents the backup file created from the database file (either a DBF or a DB2 file extension format) prepared by the user. The DBK file extension may be generated automatically by the dBASE application like in the case of the original database file becoming corrupted.

In the context of information technology, a backup file refers to the process of creating copies of the data files in order to generate additional copies which can be used for restoring the original state of the data after it its lost.

The backup file is only accessible to the program that created it. This essentially means that it is useless without its host application. However, there are instances wherein interoperability exists between certain programs under the same category allowing one application to import the backup file created by another program.

In database management, a database file backup essentially contains the same information and structure as the original but in a compressed form which makes it unreadable by the program unless it is first extracted.

Open DBK File

This file extension was developed by Appricon and categorized as a data file. It also comes in the text format. It is used by Analysis Studio, which is a data mining and statistical analysis program.

It contains mined data and it is stored in the form of a plaintext and tab-delimited format. It also includes an Analysis Studio header. They are usually used in storing data to be used for analysis online when it is connected to an Analysis Studio server; it can equally be used in online mode.

They are generally referred to as data files. Also, they can be called Analysis Studio offline data files. This format and the Analysis Studio software were developed by Appricon and the purpose was to make available to users offline analytical and data storage functionalities, as well as, analysis, management, storage, research and so on. Any user that gets disconnected from the Analysis Studio server can access it in offline mode.

Be that as it may, the Analysis Studio software also makes available user access to the content in online mode. The contents can include data encoded in tab-delimited or in plain text format.

It can contain data from different sources; examples of the sources are SQL Server and Microsoft Access databases. The files are paired with a corresponding .STP.

The .STP contains the object information and project data schema they have a tab-delimited format and can be imported into Microsoft Excel once the header information is stripped.

This extension is given to the files already created using different software applications. They are also used by the various software applications. The files are compatible with Mac, Unix and Linux operating systems. Most of them are stored in the binary format.

They can contain different types, like libraries, project, document files and several others.

How to open DATA files

If you are a Windows user, you can open it using the following programs:

• WinRAR
• WindowsR Internet Explorer
• Microsoft Office

Many of the programs highlighted above are available for free, but you will have to pay a token for some other programs.

You can launch a .DATA file or just any other on your computer by simply double-clicking on it. If you set up the association correctly, the application developed for opening it will get that done effortlessly.

There are times you will have the right application on your PC but it is yet associated with it. You can easily tell Windows the particular application to use for that. It will then become very easy to open it correctly using the right application.

It is not safe to rename the extension on this files or any other since this can change the type. You can only change the file from one type to another by using special conversion software only.

The .download file is categorized as a web file and has the Text and Binary format. It is a file being downloaded currently from the internet or a file paused or stopped while the downloading has not completed. You can continue with the downloading process by simply double-clicking on the file on the same web browser where you started the downloading originally.

.Download files are created by Mozilla Firefox and Apple Safari web browsers. When either Mozilla Firefox or Apple Safari is downloading a file, the file is automatically given the .download extension. If you are downloading greatname.mp4, for example, it will be renamed as greatname.mp4.download by these web browsers. After the file has been downloaded, the .download will be automatically removed from the file name and the downloaded file will be available for use. While the file is being downloaded, it will most probably be seen in the "Downloads" folder.

If there is an interruption in the downloading process while it is going on, you will not have a problem recovering the file. All you have to do is to delete the .download extension and then open it using the right program. If you find it difficult to open the file, then it is advisable to delete the partially downloaded file and download it again.

A file that is actively being downloaded can also be saved by some P2PP file sharing websites using the .download extension. The extension will be replaced with the appropriate file extension at the completion of the downloading.

The download process is usually monitored by the Download Manager and virtually every device has a download manager already installed. If it does not come with the device, it should be present in the web browser you are using on your device, be it a PC or a mobile device. The Download Manager is responsible for adding the .download extension to the file being downloaded and for removing the extension after the downloading is completed.

File type: MicroStation Drawing

The drawing file created by the MicroStation application developed by Bentley Systems uses the DGN file extension by default. This file supports the two- and three-dimensional drawing format normally deployed for use by the construction design application. This format file is based on the ISFF (Intergraph Standard File Format) or the newer V8 DGN specification standards.

Due to the proprietary nature of the DGN file extension, the user is provided with the option of converting it to the more commonly used DWG file type recognized by AutoCAD LDT. The MicroStation software is a CAD software package that is commonly applied to drafting and designing tasks.

This application is distributed exclusively for use under the Microsoft Windows Operating System platform although earlier versions were made available to the Macintosh environment with a few geared towards the UNIX Operating System. This application is one of the few engineering and architectural packages developed by Bentley that adhered to CAD standards and has the inherent ability of reading and writing formats in the DXF and DWG file formats.

The DGN file extension is also associated with the production of media outputs in the form of rendered image files, 3D Web pages in VRML, and animations. In this context, the application is closely associated with the BMP, AVI, JPEG, PDF, and VRML file formats.

File type: Mac OS X Folder Settings

DS or Desktop Services Store used by the Mac OS X Operating System platform is widely attributed with the creation of the DS_STORE file extension.

This specific format which is specific to the Macintosh environment is used for storing folder settings and viewing preferences of the user.

This file contains information regarding:

• The location of the folder's window,
• The size of the window,
• View options that have been defined by the user (like column, list, or icons),
• And the specific layout of the icons in the window.

This file type normally has a hidden property but can become visible when it is copied across networks, restored from backup files, or transferred to a Windows based computer system.

When the DS_STORE file format is deleted (whether intentionally or accidentally) the data contained in the folder will not be affected.

However, when the system cannot detect the presence of the DS_STORE file extension from within the folder, the Finder application will resort to the default settings for viewing opened folders.

The DBF file extension is a legacy file format from dBASE. It is  one of the pioneers in the computer industry in the field of data management.

The DBF format file represents a standard database file. To date, is utilized by the application along with other database management applications.

This format supports the organization of data into a series of multiple records. These records use an array data type to define types. It also maintains compatibility with a broad range of xBase applications or what are termed as dBASE clone applications.

The application made its debut in the computer industry via the dBASE II software. It proceeded up until the version IV of the software. Majority of these files types are supported by either Microsoft Access or Microsoft Excel.

This means that you can import into these programs under the Microsoft Office productivity suite. It is commonly associated with the NDX format file which represents the database index.

File type: DjVu Image

What is

Developed by Paul G. Howard, Patrick Haffner, L'on Bottou, and by Yann Le Cun in 1996 at the AT&T Laboratories, the DJVU file extension and its accompanying technology are marketed by LizardTech. T

his format file represents a compressed format for image files designed to provide content providers with a way of scanning high resolution colored pages and images without the matching large file size. In this aspect, it is a viable alternative for use in publishing catalogs, magazines, books, and similar media over the Internet.

It introduces a tremendously better compression algorithm in dealing with images by compressing colored JPEG or GIF image files five to ten times better than other standards and three to eight times better compression when dealing with black and white TIFF-based documents. Another distinct advantage of the DJVU file extension is that it is a free file format based on the Open-Source licensing concept.

The source code for the file format's reference library can be downloaded from the host website.

The ownership for the commercial development rights for the encoding software has gone from one company to another in the recent years. The originators of this compressed file format maintain an implementation based on GPL. This is called DjVuLibre.
