I am looking for a tool that could help me compare the contents of 2 big folders and detect what's changed in one of them (files added, modified, moved, copied) compared to the target. I also want to be able to sync the two folders using my preferences (custom sync).
I want to use this as a backup, but it shouldn't be completely automatic (I want to see what is synchronized, what's copied). The reason for this is that I maybe want to keep some files on the target (old archived projects) but delete them from the source (to save up space).
It's very important that it detects moved files/folders in the source directory (so I avoid duplicate if I do one-way synchronize -- I have the habit of reorganizing my directory structure, therefore moving folders and creating subfolders)
It also needs to be fast because I'm talking about large directories (~ 60 000 files)
So far I've tried the following software, but have not found something that could satisfy my backup needs:
- ViceVersa Pro (it's nice and fast, but it couldn't detect moved files)
- WinMerge (very slow to compare 60 000 files - can't afford time loss when doing more frequent backups) (update: this tool doesn't detect moved files either!, it's just much slower than ViceVersa)
EDIT: I changed over to Mac so now I need one that works with MacOS (not necessarily for Windows)
