Unison is good, as is rsync, but in this particular case will be
complicated (if ( understand correctly) by the use of the identical file
names for different files on the two computers. I don't see an easy,
automatic way around this. I would rename one or some of the
directories, put them on the same computer, and then manually go through
them and decide which ones are duplicates, and which are unique but
identically named files, and rename those.

If this is a Unix/Linux system, it might be useful to know that the
"diff" command can work on an entire directory, if you plead with it
sincerely enough and use the right parameters.

In future, unison or rsync could be used on a regular basis to avoid
another situation like this arising. Back in the good old days, we were
able to share disks between computers with something called "NFS," and
even further back, file versioning in VMS might have been relevant and
useful. But I am wandering.

Cheers,
