What is ASS file?

The .ASS file is a text file. This is the movie's subtitle file. It is supported by most video players. It is one of the more advanced subtitle formats. Aegisub's subtitle editing program is open source for most hardware platforms. This format includes advanced subtitle effects as well as editing and correction tools. The program, as well as the associated format, is considered to be one of the best in FanSub.

How to open ASS file?

The most common problem when using Aegisub Advanced Substation Alpha Format is that a specific ASS is not associated with the program. This is manifested by the fact that ASS files open in unusual applications or do not have an assigned program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the ASS file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Aegisub

The first step is to check if the computer has the Aegisub program installed. This can be achieved by typing Aegisub into the operating system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open ASS files.

Programs to open ASS file

Remember to download programs supporting ASS files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Aegisub with ASS files

If the application is or has been freshly installed, but the ASS file still does not use the Aegisub program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Changes can be made using the "Change" button. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. Checking the "Always use the selected program ..." box will permanently associate the ASS file with the Aegisub program.

Step 3. Update Aegisub to the latest version

The fault may also lie with the Aegisub program, it is possible that Aegisub Advanced Substation Alpha Format requires a newer version of the program.

Step 4. Check for the following problems with the ASS file

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

Very often, the file may be size 0 or incomplete. Usually this applies to ASS files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file ASS or the program directory. Sometimes virus-infected ASS files cannot be recovered, so make a backup in advance.
Older version of ASS file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair ASS file corruption.
The program can also signal the fact of encryption. The encrypted file ASS except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. It is best to move ASS to a different directory.
This problem usually affects more complex files. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. Sometimes you have to wait for the session to the file ASS to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
