SyncToy frequently tries to create duplicate files when I run a sync operation. Here's an example of what I mean:
Say Testfile.xxx is already in both the target directory and the source directory. The files have identical names, types, sizes, modified dates, etc.
Synctoy will rename the file in the target directory to Testfile.1.xxxand then copy a new version of Testfile.xxx over from the source directory.
This leaves TWO files in the target directory (Testfile.xxx and Testfile.1.xxx) that are identical in every way except for their name. Doing this can effectively double the amount of space taken by the same file, and it means I have to
manually inspect every sync preview (which sometimes include thousands of files) for duplicate operations!
The files Synctoy chooses to duplicate seem random. Why is it doing this and how do I fix it?
