    Backup / move Windows.old file

    I was going to clone my HP laptop hard drive, but first I want to move the huge folder, "Windows.old" to a NVMe hard dive (in enclosure) for archiving.
    I tried to CUT and PASTE into the external HD, but seems it did not all move over ,or only some parts.
    The folder "windows.old" was created Sept 7, 2020 by the way.

    Any trick to get the Windows.old off the C drive into a portable hard drive?

    Windows version 21H1

    I like this version just fine.

    Hi, if it really was created that long ago, that would suggest your Windows installation is way out of date- not upgraded since then. (Noted you say you have 21H1).

    Further, normally it's deleted 10 days after the upgrade automatically.

    Now Windows.old allows you to revert to the previous build- but only up to 10 days after upgrading. And you say you're happy with 21H1. So why would you wish to keep it?

    Hello @Gibbs,

    Out of interest, why do you want to keep it ?

    You will be better off creating a System Image.

    Have a look at this > How to Delete Windows.old and $Windows.~BT folders in Windows 10. I know it refers to deleting it, but it also says that the Windows.old folder gets automatically deleted after ten days anyway.

    The Windows.old folder contains a copy of the previous Windows installation, so that is why I suggested creating a System Image.

    I hope this helps.

    It can be done from booted media, winpe/re etc.

    From inside windows one easy way is with dism++ file explorer. Click it and a browse window opens which will let you move/delete etc similar to what you could do when booted into winpe. Another way is with nsudo, but dism++ is simpler.

    I followed the links and used the option of "Settings" and "Storage" and deleted the previous Windows installation folder. It is now gone.
    I also downloaded a batch file to delete that $WINDOWS.~BT folder but it i not nearly as large (69 GB) as was the Windows.old file.
    I guess I have not had a reason to use that windows.old folder for some time, so might as well delete it.

    Often my wife and I wish we had stayed with Windows 8.1 pro.
