So I ran the duplicate file program, and it found almost 14 megs worth. At least 2 of each duplicate found. For example:
File:  Folder: Size: Duplicate of:
Minutes of Meeting 40 beta (1).png (folder) (size) Minutes of meeting 40 beta
Minutes of Meeting 40 beta.png (folder) (size) Minutes of meeting 40 beta (master)

Before I remove all these duplicate files that have been found, I want to be sure that PM is keeping an original, or do I need to delete just one of these?

How do I know which ones to delete, without causing a crash, or program failure?
