    PS CS3 unknown file type (?)

    auctioneer Community Member

      Hi

       

      I've been working in PS CS3 with some images and went to open them tonight and PS gives me an error 'unknown file types' these images were created in PS CS3 and are .jpg

       

      Any ideas?

          Do you have finder set to show file extensions?

           

          If you aren't careful when saving, and when you rename a file from untitled.psd (default for new files in PS) to (name).jpg the extension can drop if you switch the file type first and then change the name. It may appear to save it as a jpg, but if it dropped the extension, the Mac Kernel will tell PS that it is an unknown file type, or a generic document and you'll see the error. Without showing extensions in Finder, you're none the wiser when it happens.

           

          Finder>Preferences and Advanced. Check the box to show extensions. Then look at the files to see if the extension dropped when you saved them.
