What is ATR file?

The file with the extension ATR is the Disk Image Files file type. It was designed by Atari. Disk Image Files consists of 203 similar files. Atari Disk Image is supported by 1 operating systems. The file will work on Windows systems, unfortunately not on others. Alternatively, you can use 2 other programs. The SIO2PC, ZipZag programs will also handle the file when the PC Xformer Classic program does not fulfill its role.

How to open ATR file?

The most common problem when using Atari Disk Image is that a specific ATR is not associated with the program. This is manifested by the fact that ATR files open in unusual applications or do not have an assigned program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the ATR 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 PC Xformer Classic

The first step is to check if the computer has the PC Xformer Classic program installed. This can be achieved by typing PC Xformer Classic into the operating system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file ATR with PC Xformer Classic. Below is a list of programs that support the file ATR.

Programs to open ATR file

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

Step 2. Create association of PC Xformer Classic with ATR files

However, it may happen that the application itself does not cause the ATR file to open in the PC Xformer Classic application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can select the desired program. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. The "always use the selected program ..." field will set the PC Xformer Classic application as the default for handling the ATR file.

Step 3. Update PC Xformer Classic to the latest version

If, despite the association of the PC Xformer Classic program with the Atari Disk Image file, the file still does not open, check the program version and possibly update it to the newest version.

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

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

Very often, the file may be size 0 or incomplete. This suggests truncating the ATR file contents when downloading or copying. Downloading the file again should fix the problem.
The computer may have fallen victim to a computer virus or hacker. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the ATR file that we want to open. Sometimes virus-infected ATR files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the ATR files changes over time. 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 this. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair ATR file corruption.
When reading, a message appears that the file was encrypted or corrupted. The encrypted file ATR 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. If possible, you can try to move the ATR file to another location.
This can happen on a file that does not support multiple access. In this case, the ATR file is blocked by the first application to open it. Closing other programs should help. If the error persists after closing other programs, wait for a while. However, some background programs may block the ATR file while scanning. If nothing helps, please reset the device.
