Question : Need a quick app/script to compare two large folders for differences (and list/log them)

Hi All,

We are testing out some restore procedures.  We have our live data folder (20 GB) and a restored copy from an online backup (which comes out to about 16 GB).  We expect it to be smaller as certain file types are excluded (.img, .exe, etc) online.  

However, we are looking for a quick way (without writting a script from scratch and reinventing the wheel) to compare the two folders (which under them have 1000+ sub folders so by hand would take forever) and see exactly what's in the live data that was not in the only restore so we can be sure.

Really not sure what zone to throw this in, putting it under batch and dos.  Thanks!

Thanks!
