In Windows 10, I have a bizarre problem copying folders to a 128 GB USB drive that's listed as having an exFAT file system.
I've tried copying folders from my hard disk and from a 32 gb USB drive that shows up as FAT32.
Some folders show the right files in them; but several *appear* to copy correctly, showing good listings of files, but when I subsequently "eject" the 132 GB drive, and then plug it in again, the files are not there.
I've tried copying whole folders, and individual files, and the result is always the same: initi8ally they show up, but subsequently they are missing.
One clue: when I do a COPY from either my hdd or the USB drive, the following message shows up: "Compressed Folder. Please insert the last disk of the multi-volume set and click OK to complete."
The same thing happens when I create a new folder on the 128 GB drive and copy individual files to it--they are gone when I EJECT and subsequently re-insert the thumb drive.
So, 2 obvious questions: what's going on here, and how do I copy files to this drive?
