Photographs and Powerpoints won't open

Jun 13, 2018
I am using Win 7 on my laptop. I have folders that I placed photographs in awhile back and now I can't open those photos. If I open the folder, I get a message that the file is empty. However, if I check on the properties of the folder, it will have several mg in it. If it has mgs of contents, then how can it be empty? Is there a way to fix this problem? I have a similar problem with Powerpoint files. Thanks.
