Mass copy files securely and fast, even resuming, with multi-threaded RichCopy
Microsoft RichCopy is a free utility that will let you copy several files in parallel and pause/resume copy operations at any time. Rather than copying one file at a time in serial order, RichCopy opens multiple threads simultaneously, allowing many files to be copied in parallel and cutting the total time required to complete the operation several times over.
You can also pause and resume file copy operations, so if you lose network connectivity at any point, you can just pick up where you left off. RichCopy is designed to help people who copy huge number of files between storage devices by accelerating copy performance and shortening the time for file copy operations.
Main Features: Profiles storing different settings. A user can easily switch configuration by choosing a different profile. Multiple sources – you do not need to run multiple copy process when the source directories are different; just specify multiple sources that need to be copied to the destination directory. You can run more than 256 threads. Filter files and directories with any date/time stamp, ‘earlier” and ‘later’ conditions, ‘copy’ and ‘not to copy’ conditions. Command line support.
I found RichCopy to be a trustworthy, fast and convenient application.
