A few days ago I was working on a project but then a few days later when I tried to put it on a doc it didn't work and when I tried to open the file directly on photoshop, it had disappeared when I double clicked on it and now I can no longer fing the files.
Which version of Photoshop and macOS are you using? Where did you save the files? Is it a PSD file? Does it happen with all the files? What happens when you try to open it? Do you get any error messages?
