Files That Will Not Open In Photoshop
Sometimes you will get a dialogue box in photoshop when you are trying to open a new file. And it says "Could not complete your request because an unknown or invalid JPEG marker type is found" or " Could not complete your request because it is not the right kind of document."
I don't know why this happens sometimes, but all I can advise is that it may have something to do with the download being corrupted.
I have also found that this is usually an issue with Windows, and very rarely happens on Mac.
The below solution has worked for most customers who have had this problem.
- Open the image in a photo app such as Preview (on macOS) or Photos (on Windows). (if you have paint that will work just as well. )
- REMEMBER to save the file as a COPY, so the original file is kept. This will require renaming the file, e.g. With the text "copy" added at the end.
- Now you can save the file again as a JPEG or PNG image from within such an app. Try opening the file again in Photoshop.
- This should resolve the issue.
ALSO it may help to MOVE the file folder to another location. Sometimes this is all it needs!
