What is APT file?

The file with the extension APT is the Text Files file type. Additionally, the Text Files category contains 440 of other files. Almost Plain Text Format is supported by 3 operating systems.

How to open APT file?

The most common problem when using Almost Plain Text Format is that a specific APT is not associated with the program. This causes the file APT to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the APT 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 Text editor

In this case, you should first verify that the Text editor application is installed on the computer. To do this, enter the name Text editor into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support APT files.

Programs to open APT file

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

Step 2. Create association of Text editor with APT files

If, despite the installed application, the APT file does not start in the Text editor application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. 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. Using the "Change" button we can set the program to handle this type. 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. The "always use the selected program ..." field will set the Text editor application as the default for handling the APT file.

Step 3. Update Text editor to the latest version

The fault may also lie with the Text editor program, it is possible that Almost Plain Text Format requires a newer version of the program.

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

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the APT file. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the APT file that we want to open. Sometimes virus-infected APT files cannot be recovered, so make a backup in advance.
Older version of APT file may not always be supported by the latest software version. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair APT file corruption.
The program can also signal the fact of encryption. The encrypted APT files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some of the system directories are excluded from modification. The problem is only writing to the file, not reading it. If possible, you can try to move the APT file to another location.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the APT file for a certain period of time. If nothing helps, please reset the device.
