Background: Customer has been using a folder syncing tool that has not worked for many weeks. The tool was (supposedly) keeping in sync a set of files & folders between several computers. As it hasn't worked for a while, many files were changed on one or more computers without syncing to the other computers. So both versions might need to be kept. Now we need to clean the mess
Question: I am wanting to find a (paid or free) tool that can compare the files in the folders, then merge the folders taking some predetermined actions like
1. If file content (file hash) is the same (even if the date is different), do not copy
2. If the file content is different, rename each file, adding the file owner & last modified date to the file names
3. and (can I dream...), if the files are identical but located in different folders (same file hash, different folder) then ... do xyz (not sure what yet!) ... as we know that some users took it upon themselves to re-organise their version of the files & folders in a more logical manner (Sigh)
Have you used a script / or application that can help us clean this mess?
