Hello - Windows 11 - just had a session copying files from memory sticks to a USB attached drive as a precursor to wiping old stuff from the memory sticks. The idea was to get several years of files into 1 place and release the memory sticks which were getting cluttered!
PC didn't like copying some of larger files from USB memory stick to USB attached SSD and the computer "hung". Found went OK copying from memory stick to PC SSD then copying PC SSD - USB attached SSD.
HOWEVER since this exercise I keep getting the same "rogue files" appear in each PC SSD root folder.
I delete these files and folders and they reappear?? HELP please!
Very annoying, Mel

2026-10-14T20:51:20.9066667+00:00 Reading around they could be "test files" placed by the antivirus prog?
"it is a kind of temporary files to detect an unknown virus, they create the file, and check after access it, if there is an unknown virus it will infect the file, and AV software will detect it. It is very simple but clear method" could be?

2026-10-16T20:11:03.5+00:00 Hello all - the ANSWER seems to lie in the fact that I had my view set to see "hidden files".
It has been pointed out by others that many antivirus programs plant these simple files as they will be "attacked" by a virus.
Their content is innocuous. When I set Windows to not display hidden files and folders they do not appear.
QED, Mel

2026-10-14T22:50:03.4933333+00:00 I do not think this is a good behavior of antivirus program.
Please check if the problem exists during clean boot and in the safe mode.
Tell the result.

2026-10-14T20:45:27.5+00:00 Do you mean that all four drives you connect using the single USB adapter? If yes, this is adapter's problem likely.
