I am doing a copy operation from a server to a harddisk and from that harddisk to another server (on another network) I want to be sure that everything is copied correctly, ? which tool can i use to pull a report to check whether everything was copied correctly. Important is that it should be able to run on a very large folder (700 GB). I received FileCheckMD5 from someone but it crashed with out of memory errors. **There is no physical connection between the two folders !** ## Deliverables * * *This broadcast message was sent to all bidders on Thursday Aug 26, 2010 3:57:14 PM: Important is that it should be able to run on a very large folder (700 GB).
