[plug] Merging two directories

[Shanon Loughton]

HI all

I need to merge two directories, which are fairly large ~4GB each.

A copy of the original dir (dir2) was taken two weeks from the
original (dir1) and altered over that time.  Need to merge dir2 back
into dir1.  I can find differences with diff or find.
Some files are newer and *smaller* which are suspect and need to be
manually analysed, thus either flagged or left alone by the tool.

Anyone know a good tool I could use??

thanks
Shanon
