AML Format

AML file stands for ACPI Machine Language File. The developer of the file format was The ACPICA Project. And it is highly popular. It belongs to the System Files category and has a Binary format. The file is a system file in the Advanced Configuration and Power Interface (ACPI) Machine Language (AML).

It is also a low-level of language to configure various hardware properties. The file is usually for booting Mac OS X on hardware not related to Apple. Usually called ("Hackintosh" systems). A good example of it is the P55 motherboard. The system file is equally to enable better compatibility with hardware, as well as, to improve the performance of a system.

The AML file contains a Differentiated System Description Table (DSDT). And this is designed to store instructions that help in notifying the Mac OS about several hardware settings. The AML file is better in the root directory when you download and install it on a Mac OS X system. This is to be easy recognize it.

You can check tonymacx86 for series of AML files that are already for Mac OS X. The end-user can also customize and edit the AML file using DSDTSE, the handiwork of EVOSX86 team known for software development. You cannot edit AML files directly. However, you need to first decompile them into ".dsl" files after which you can edit them. And also then compile them back into their original ".aml" files.

AML files are with instructions at the level of ACPI, which is between the operating system and the BIOS.

How to open the AML files

The AML files might have been designed for Mac OS. But you can open them on various operating systems. l.

In Windows

You can use the programs:



You can use the software:

  • iasl

In Linux

You can use the software:

  • iasl



You can use another program to open the AML files. Double-click the file and click on ‘Open With". A series of other programs that can be sued to open it will appear on a drop-down menu. Some of the other files software to open the AML files are below:

  • Morpheus Photo Morpher Layout Project
  • AutoMage
  • Mio Technology Application Markup Language

You can download any of the files above from the developers' websites try using it to open the AML files.

There are some file extensions that you can use to open different types of files. You can easily open a file by first know the type of file it is. Many of the AML files available are System Files. You can open them using different kinds of software packages. If you have a program on your computer system capable of opening System Files, then it is possible to use that program to open AML files.

To know the type of file the AML file is:

  • First check the properties of the file.
  • Right-click on the icon.
  • Then selecting "More Info" or "Properties".


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.




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.

How to open Dfont file

One of the best ways to open a dfont file is to convert it to another file. For one, you can convert it to other file formats, like svg, bin, otf and tff. The conversion makes it easier to open the file. The method adopted in opening Dfont File depends a great deal on the particular operating system that you are using.

In Windows

You can use in windows operating system one of the following programs:

  • File Viewer Plus
  • fontSplitter.



In MAC OS these are the available programs:

  • Apple Font Book
  • DfontSplitter.

You can equally open Dfont File using Font Book. Also using various other Mac Os X programs that have access to the system fonts. If you still have a problem opening the file, you can get in touch with field experts or automatic tools.

Python comes with a built-in function that can read, write and create files. You can use it to even create text files or append any data to your chosen file. If you like, you can equally use Python to read files from one line to another.

The File Modes in Python make the program even more interesting than ever. In the remaining part of this write-up, we will teach you some very exciting things about Python and how to use it for opening a file.


How to open and read files with Python

If you want to open a readable file with Python, you need to first open the file in a “read mode”. Bear in mind that contents of Python are available in the .txt file and the file to be opened in Python will be opened in this format. The following steps can guide you through the process involved.


  • First of all, open the file in the Read mode by using the code: f = open ( “filename.txt”, “r”)
  • Next, you should use the mode function in that code provided above and this will help you to check if the file is available in the open mode or not. If it is available in the open mode, you can go ahead with the process. the code to use is if f .mode == ‘r’ :
  • After this, you can use for reading the file data and then storing it in variable content  using this code: contents =f .read ()
  • Afterward, you can then print the contents that you have opened.

Reading the opened text file line by line

As stated above, the files opened with Python can be opened in the .txt format. And the text file can be read line by line if the content of the file is so big that it is difficult to read all. Reading from one line to another helps a lot to prevent any form of complication. Python will help to segregate the data to be read. And present it in a mode that is very easy to read.

First of all, run the code (f1=f.readlines()) and this will help you to read the document or file in question from one line to another. Running that code will help to separate each of the lines from one to another and make the file or document available to you in a format that is readable.

If the line is readable and short, the final outcome will have a similarity to what obtains in the read mode. However, the reverse is the case if the file contains complex data; such a data is not readable and the code given above can make it readable.

Some file modes to take note of in Python

  • ‘+’ mode will help to open a file for writing and reading; writing also translates to updating
  • ‘r’ mode is described as the default mode and it opens the file for reading
  • ‘b’ mode will help to open the file in binary mode
  • ‘w' mode will open the file for writing it can also be used to create a new file if the file fails to open, probably because it does not exist. It can equally truncate the file if it exists.
  • ‘x’ mode will help to create a new file. The operation will fail if the file exists already.
  • ‘a’ mode will help to open the file in the append mode. It will equally create a new file if the file is not in existence.
  • ‘t' mode is the default mode and will get the files opened in the text mode.

In summary, you can use the readlines functions in Python for reading the content of a document or file one after the other. You can also use the read function for reading the whole contents of the document or file. Furthermore, you can append data to any existing file by using the command open; that is, “Filename”, “a”). the function open ("filename", "w+")creates a file or document; the + commands the Python compiler to create the document or file if that file does not exist already.

Checking if a directory or file exists

Also, you can use Python to check if a directory or file is in existence or not. We can use a built-in library function to carry out this task. You can use any of the following functions to check if that directory or file is in existence or not:

  • os. path.exists()
  • os. path.isdir()
  • os. path.isfile()
  • paathlib.path.exists()

Methods for Python copy file

Python comes with several built-in functions. They can help to copy files easily using the utilities from the Operating System Shell. First of all, you should get the path that leads to the location where you saved the original file in the current directory.

Explanation of the code

First of all, we will check if the “filename.txt” file is in existence or not. If it is in existence, then we will proceed with the process. We will then store the file path in the “src” variable since the file exists. After getting the path, we will separate the file name and the path from each other. We can do this by using the split function: path.split on source variable. After executing the code it will create a print out with “file path” and a “file name” separately.

We can then create another copy of the already existing file by using Shutil Module. You can take the file named “filename.txt and add another extension to the end, “.bak” so that the new file name will look like filename.txt.bak.”  The new file with .bak extension will represent the new copy or duplicate of the original file. Next, we are to use the function of the utility's copy to get a duplicate of the original destination. After running the code, you will get a duplicate file bearing the .bak extension and you can find it on the right end of the panel. Always remember that the Copy function can only copy the content of the file without copying any additional information.

File type: ARJ Compressed File

The ARJ file extension is used by the compression utility to reference the compressed archives generated by the application. ARJ is basically an acronym for Archived by Robert Jung in obvious reference to its developer.

This compression tool first made its way into the IT market during the Disk Operating System days. Up to the earlier versions of the Microsoft Windows Operating System environment.

With the inception of the more advanced Graphical User Interface (GUI) Microsoft Windows 95, the ARJ32 version of the compression tool started. This 32-bit console version remained very popular until the Microsoft Windows 2000 platform.

This compression tool was primarily noted for its creation of highly efficient compressed archive files that support the 16- and 32-bit computing architecture of the Intel processor. ARJ became one of the only two mainstream archiving utilities for the MS-DOS and Microsoft Windows Operating System platforms in the middle of the 1990s.

PKZIP compression utility was the main competitor of the software during that era.

How to Open an ARJ File

Category: Compressed Archive
File format: Open-Source
Open with Windows:
  • ARJ,
  • ARJ32,
  • Zipeg
Open with Linux: ARJ for Linux
Some components of the ARJ software that support the ARJ file extension are  under the 5,140,321 U.S. Patent.
Although generally less popular compared to PKZIP, it had a substantial niche in the computer market. Especially for BBS users up to the warez era.
The preference for the use of the ARJ format file is largely attributed to the application's ability to create and handle multiple archive volumes. It does this by splitting huge files into smaller chunks making it suitable for dial-up connections as well as software distribution via floppy disks.
It also has proven to be more powerful in terms of compression capability than PKZIP.
The main limitation of the ARJ compression tool is its lack of support for a graphical user interface remaining mainly command line based despite the introduction of GUI based Operating System platforms.
The application responsible for generating the .ARJ supports the use of long filenames, data damage protection, files version management, and ANSI display handler sequences among others.


File type: Windows Media Video File


File Extension WMV

WMV stands for Windows Media Video and it is a video file format that has been developed by Microsoft Corporation and is a proprietary video format. The WMV format has been based on Microsoft's Advanced Systems Format or ASF format container and it compresses videos with the help of Windows Media Compression. Essentially .ASF files are the encoding that the video files use in the Windows Media Video format files. The WMV format video compression is a very crude compression technique being a completely proprietary compression algorithm it is not easily convertible to other video formats. However it is possible to do so and there are softwares available that do that.
