Windows 10: Why is it giving me the error "Not enough space in x - personal to copy files"

I've got a very large file in my desktop folder, I won't go into it too much but I think it's like 30-50gb and it's stuff I got off an old hard drive before it died. I got a new pc and the files are very important so I made a copy onto it from a usb. I want to get the files onto a different usb instead of having them on my pc as I need more space but when I try to send the folder they're in to my usb, I get the error I stated in the question. My usb is about 130gb with 2kb of files on it so it's got enough space. I don't see why the personal folder would matter though because I'm trying to mov

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

Issue was the above, so thanks temp02.

 

music files with an X on them

Not that I have a solution to suggest, but I think it is interesting that only three of the eight files in your list have that gray X. Are you able to copy those files which do not have the X? That might lead to a clue as to how the files got created, etc.
