and upgraded to OS 10.7.5 and still the same error.

    Have you installed all the updates for Photoshop CS5?

    Does this happen with all file types?

    Can you post the PSErrorLog.txt file in your preferences folder?

  • Hi Chris,
    I am on 12.1 and it is happening with all files.
    It is an issue with my user account and PS as I have
    a service user where photoshop worked ok.
    I was desperate so I have now used Time Machine to
    go back to last week, unfortunately I forgot to save the
    PSErrorLog.txt file first.
    I think the issue arose due to a client sending a file with
    the wrong extension. This is not unusual, PS doesn't recognise
    file type and then I change the extension until I get the correct one
    for the file, bingo it opens.
    On this occasion I tried all the usual possible extensions without
    any luck but unfortunately I couldn't open any other files after
    Thanks, James

      Photoshop does recognize MacOS file types, but those get lost when copying to non-Mac file systems, and when sending via email and most cloud file transfer services.

      But a file shouldn't change Photoshop's ability to open other files.

      If this happens again, we really need to get to the bottom of what went wrong - and the error log should offer some hints (it doesn't always, unfortunately).
