Robocopy
In an event when a user requests for a desktop/notebook reformat/reimage or file transfers, one crucial phase when copying-over or backing up of large files such as PSTs, image files such as *.WIM, *.GHO with more than 3-4GB of file size on a normal GUI copy-paste there’s a possibility of getting these files corrupted. One tool that I find very handy and reliable is the Robocopy. So far all the PSTs and image that I’ve backup/copy have not encountered any problems after using robocopy to transfer those files: Running ROBOCOPY help in CMD
