    slow complicated file copying

    I am using Win10 10240. I have a problem copying a large number of big files. The setup is a bit tortuous.

    The source is an old WD Cloud NAS on ethernet via my ethernet connected router.
    The destination is an external hard drive on USB3.0

    Using file explorer, I drag a bunch of folders to the destination and copying begins but either stalls soon after or indeed never starts.slow complicated file copying-win10copying.png When it works the speed is around 10Mp/s but why does it stall at random places?

    I've tried just copying a single folder too. Single files are OK. I've looked at the resource monitor and so on and can't see anything odd although I'm no expert there.

    I don't know of any other way to get these files across. The WD Cloud software is hopeless and not fit for purpose in my view. Would a command line xcopy batch file be better? Or third party stuff?

    I'd try xcopy or robocopy.

    Have you tried leaving it for a day or two until the cack-handed algorithm has verified all the files are valid to be copied and there's enough destination space, heh.

    Yeah, an xcopy batch file is likely to be a ~million times faster.

    Move the WD to the physical computer. Some routers have really slow CPU's and not enough RAM, to handle everything.

    Very much agree. This is almost certainly the problem.

    Windows 10

    In the past many users used a program from Microsoft called Windows Easy Transfer. Windows 10 does not have the Windows Easy Transfer program anymore. You will need to use a tool like PCmover from Laplink to get your apps, data and setting from your old PC to your new Windows 10 computer. Microsoft recommended it and provides a limited use free copy on their site at Free data transfer.

    This program transfers files, and setting only. You can upgrade to the Pro version of PCmover for a discounted price of $19.95 (it is usually priced at $60).
