Cant Open File?

[Anonymous]

I've been working on a project in sketchbook for a few days and when I tried to find it in my photos, it wouldn't appear. I then went to my files to find it and it showed up with a paintbrush as the thumbnail instead of the drawing itself. When I tried to open the file in sketchbook, a popup telling me that I was unable to open the file appeared. Is there a way for me to fix this file and open it again? (This has happened to me one time before but I didn't care about the lost file as much as I do this one so I brushed it off.)

I am sorry to tell you that this file has been corrupted and won't open anymore.  In the future, use the Save As option to save your file.  By using the "Save As" option, it will add a number to the end of the file name.  i.e. File > Save As > Dragon.tif > File > Save As > Dragon1.tif, Dragon2.tif etc.
