So I have a bunch of really important drawings in PSD format. I wanted to rename them and I did so through SAI, because I could see their thumbnails with it in order to name them accordingly, but I did not add ''.psd'' and now I can't open them at all, not even after adding the ''.psd''. None of my drawing programs recognize them as existing, but when I added the ''.psd'' they were listed, but I couldn't open them because they are ''not supported''/ PLEASE help me recover them. If not as PSD, then at least as PNG, anything! 🙁
