I am trying to upload an image that is on a "My Documents" file to Photoshop for editing. After I edited the image, I tried to save the changes, but a window pops up (in Photoshop) to say that I cannot save the file because it is locked and asks me to click onto "properties" in windows explorer to unlock the file. I clicked but I have no clue how to unloak the file. Can anyone bail me out???
