    A Terrabyte of files copied to a win10 drive have disappeared.


    So I've got a very strange problem with files disappearing.

    I've bought a new hard drive for my sister and installed a new windows 10 on it (x64 home, whatever version the installer tool downloads these days). I unplugged the new drive from her computer, plugged it into mine (x64 pro v1909), and copied all her old files onto it. I confirmed that her files were still readable from the new drive, unplugged it from my computer, put it back into hers and booted it up.


    The terrabyte of files I copied to the drive are gone. Her Windows reports that the drive is still empty, save for the few gb win10 occupies. I put her drive back into my computer, and the files are still gone. My windows reports that the drive is still half full anyway. A file system scan and repair corrected the used space back down to just a few gb. I tried copying a few more files to it and booting it up in her computer again, and the new files disappeared again.


    I tried updating her windows and running a file system scan and repair, but both failed. I tried restarting, but her windows failed to load, giving an NTFS file system error. Probably because of the scan and repair i did on the drive while it was in my computer, but it's a little odd that it would boot the first try after that, but not the second. I Reinstalled and fully updated her windows and it still works fine, so I don't think it's a problem with the new hard drive. And I didn't sign in with any microsoft accounts, so I don't think OneDrive could have anything to do with it.


    So this is seeming like it's some sort of win10 security system? It's like it keeps a backup of the master file table and overwrites any changes whenever it boots? Whatever's happening, can I make it stop?

    I can still transfer the files via a usb drive if I have to, but I'd really like to figure out what's happening here - even if only to make certain that it's not the new drive's fault.

    :)

    how to copy files from the CD to the Computer drive

    Hi Hankriegler,

    I would suggest you to follow the steps below:


    • Press Windows key + X.

    • Click file explorer from the list.

    • Select the CD/DVD drive and hit Enter.

    • Select the files you want to copy from the CD/DVD, then select the drive where you want to paste or save.
    I hope the information is helpful.

    Thank you.

    Java.nio.file - Copying files

    You can't copy a folder, thats why it generates an exception (you are trying to copy a folder using a copy file function).
    You probably need to list all the files inside that folder and copy one by one
