Error: not a valid Photoshop document

Error

When you open a file, you get an error: "Could not complete your request because it is not a valid Photoshop document."

This can occur when you save a different file type, for example a JPEG, with a .psd extension in the file name (mydocument.psd).

Solution

Rename the file so that the file name extension matches the correct file type. (mydocument.jpg)
