Secret to Copying Large Files Fast (VHD, ISO) – Richcopy download available here


I have had literally dozens of people ask me if there is anything they can do to increase the performance of copy when copying lots of files especially large files.  I always turn them on to one of my favorite tools is RichCopy. Hint, if you want more options click View – Advanced.  More on the tool when I get a chance.

  1. I'm also a big fan of XCOPY /J in Win7/R2, when copying extremely large files. For older OSs you can use ESEUTIL /Y but it's a bit limited.

    Also worth noting that Robocopy is now in-the-box, and supports multithreaded copy.  Particularly useful when copying large numbers of files over slow links.  /MT option, plus it lets you specify number of threads.  (Default is 8)

  3. RichCopy has stagnated says:

    RichCopy has stagnated.  It has long outstanding problems with things like long file paths.  Check the comments here:

    Ken Tamaru (Microsoft) said "Long path, reparse point, some missing command options, etc will be addressed in next release. It will be released in a couple of weeks."  That was back in January 2010.  A couple weeks has turned into the greater part of a year.

    I noticed that the post you referrenced was almost a year old and it specifically said the fix for it would be out in a couple weeks.  I wonder if that is old news?  I sent an email to the author and will post his response as soon as I get it.

  4. Ken's Response? says:

    I assume you received no response from Ken regarding the fixes for RichCopy?

     

    Correct.  He is buried with new development and cannot take the time to make any changes.  Sorry.
