Windows 10: Can't copy any files to USB or Format it but "Read only" is set to "No"

I have a USB flash drive with a lot of files on it. I have tried clearing the read-only attribute in run, and in regedit but still, it hasn't changed. Also, the delete volume in computer management is greyed out. Is there anything else I should try?

USB flash drive won't read, wants to format.

What file system did your friend use to format the USB flash drive?
Linux, MAC, Windows, etc.... if, he did the project on a different file format; the system may not think there is anything useful and wants to format it to make usable.
Or, the drive has gotten corrupted (like your friend pulled the drive before it was finished and the file table/partition info/etc. is corrupt).
Static could have gotten it, too.

One of many recovery apps:
USB Flash Drive Data Recovery Software

Google has a sh*t load software to recovery and/or repair usb drives; but, be careful and always scan your downloads with a good a/v package.

Part of the commands and results were missing from the image.

Open adminstrative command prompt and type or copy and paste:

list disk
select disk #
(replace # with the disk number for the flash drive)
attributes disk clear readonly

If the above steps work then you are set.

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
