How to open ATP files

Did your computer fail to open an ATP file? We explain what ATP files are and recommend software that we know can open or convert your files.

What is an ATP file?

ATP files are Atari 8-bit Protected disk image files, which you can read more about below.

The ATP file extension indicates to your device which app can open the file. However, different apps may use the same file extension for different types of data. So an ATP opener may not be able to open all kinds of ATP files. In this case, though, we only know of one specific use.
