I am looking for a multi-threaded file copy program. The reason I'm interested in mult-threading is that I have 240 GB of files (most being pretty small) I need to transfer.

In Windows land there is Robocopy, Richcopy, Teracopy, etc. In Linux I can't seem to find any tool that can do this.

Is there any tool you all are aware of that does multi-threaded file copying?

    wouldn't multi-threading i/o be bad? Just curious. HDDs can only do one thing at a time, which is different from CPUs which can run many commands at once. – user1974 Apr 19 '11 at 03:41
  • I agree, if I try to have my computer do two different hard drive-intensive tasks, I thrash my hard drive and it can't do either task very well or much of anything. It can get so locked up that I have to reboot, so no, you do not need multi-threaded file copying. – Jeremy Bicha Apr 19 '11 at 05:11
  • @user1974 @jbicha I have found a definite speed increase when using multi-threaded file copying programs. There is though a wall at around 3-4 threads where any more and your just slowing things down. I also have to ask if this was proven wrong, why are there so many programs that do this? – TheLQ Apr 19 '11 at 20:35
  • What about rsync? Do not know if it is multi-threaded but it can resume. – N.N. Dec 25 '11 at 21:23
  • rsync is highly unoptimized, the fastest it can do on a modern cpu core is 250mb/sec. I can do 1.6 GB/sec using "cp" and 250mb/sec using rsync – John Jan 21 '19 at 23:56

Try ultracopier - teracopy alternative you can use in ubuntu, windows and mac! I've been trying to get an answer for my question on how to make this the default app how can i make ultracopier handle cut-copy-paste function in nautilus? But its still pretty useful if you have large number of files and have to copy them to multiple destinations or need to pause in-between copying!
