What is an ATN File?

Question: What is an ATN File?

Did you find an ATN file on your computer and wonder what program should open it? Maybe someone emailed you an ATN file but you're not sure how to use it. Perhaps you tried to open the ATN file but Windows told you that it could not open it.

Before you can open an ATN file (assuming it's even a file format that's intended to be viewed or edited), you'll need to determine what kind of file the .ATN file extension refers to.

Answer: A file with the ATN file extension is an Adobe Photoshop Actions file.

Other types of files may also use the ATN file extension. If you know of any additional file formats that use the .ATN extension, please let me know so I can update this information.

How To Open an ATN File

The easiest way to open an ATN file is to double-click on it and let your PC decide which default application should open the file. If no program opens the ATN file then you probably don't have an application installed that can view and/or edit ATN files.

Warning: Take great care when opening executable file formats received via email or downloaded from websites you're not familiar with. See my List of Executable File Extensions for a listing of file extensions to avoid and why.

ATN files can be opened with Adobe Photoshop.

If you know anything else useful about ATN files, please let me know so I can update this page.

Tip: Use Notepad or another text editor to open the ATN file. Many files are text-only files meaning no matter the file extension, a text editor may be able to properly display the file's contents. This may or may not be the case with ATN files but it's worth a try.

If you find that an application on your PC does try to open the ATN file but it's the wrong application or if you would rather have another installed program open ATN files, see my How To Change the Default Program for a Specific File Extension guide for making that change in Windows.

How To Convert an ATN File

There are two main ways to attempt to convert an ATN file to another file type:

The first option involving opening the ATN file in its native program is preferable because it's both easier and will probably result in a more accurate file conversion. Of course if you don't have a program that opens ATN files, a third-party file conversion tool (the second option) could be very useful.

Important: You cannot usually change a file extension (like the ATN file extension) to one that your computer recognizes and expect the newly renamed file to be usable. An actual file format conversion using one of the methods described above must take place in most cases.
