I have yearly backups of all my files on the harddrive.
The problem is that the Backup from 2007 contains files which don't exist in 2008. And I need both Versions of the Files, when they are different. So I can't overwrite the old version of the file with the new one.
I need a program which merges two folder structures. When the File from source and destination has the same content(Checksum or so) don't copy it. When the content is different copy it with Filename(1) for example.
Can anybody please give me a hint?
