This is a bad idea. If the files were accidentally deleted, their recovery could be imperiled by writing new data to the drive, such as would occur were you to edit and save other images, or if the computer decided to automatically run its defragmenter. The safest thing would be to turn off the computer totally and take to a shop before using it again.
Thank you for your response, Bayou. The missing files are on an external hard drive. I stopped using that drive when I ran into this problem. The remaining files are on a different hard drive, so I won't be using the drive with the issue. I think that will keep whatever remains of the missing files as safe as possible. Thank you for the warning, though.
