I am working on a file in Photoshop but I do not know which kind of format the file is. It is the first time I see 'application/vnd.adobe.photoshop' under File->File Info...->Descripton

enter image description here

The information on internet is not clear about it.

It seems it's a file created in photoshop, most likely .psd.

I would try using open as and trying out diffrent programs if it won't open in photoshop. You could also try using a converter if you don't have anything to open it.

  • That's it! I made the test right now, and yes, it is a file which was created inside a psd file (let's say) before being exported to another format. Thank you:)

  • Good you found the problem, it was a bit of an odd one Feb 23, 2015 at 18:15

This is called a MIME type.

"application/vnd.adobe.photoshop" means the file is: an application; vendor is adobe; application name is photoshop.

Normally when I see "format" I think it is telling me that the file itself is of that type (which would mean your screencap is photoshop), but depending on the context, it may be telling me that what is listed is the required program to open or view the file, in which case your screencap is of an image file which Photoshop has announced to/registered with the OS as being the default viewer.

If it is not a PSD, it is likely a TIF, JPG, or PNG. You might try "open as".

(note that a PSD file would normally be 'image/vnd.adobe.photoshop')
