Many teachers absolutely adore IIAB's zero-hassle content-sharing from USB sticks (their content appears nearly instantly at http://box/usb without the bureaucracy of an LMS) but recently it's become unbearable, as prior sticks' directories keep accumulating without being deleted.

Specifically, /library/www/html/local_content quickly ends up containing a flood of subdirectories, arising from "every" insertion of USB memory stick(s) — somehow creating yet more directories, even when the very same stick(s) are later re-inserted into IIAB. This ever-growing flood of stale/bogus directories[*] needs to be deleted (somehow) as soon as is reasonably possible anyway:

USB0
USB1
USB2
USB3
USB4
...

[*] Does anybody idea know why these stale/artifact directories above (USB0 etc) are sticking around & cluttering up /library/www/html/local_content much more than in the past?

I also see symlink on the usb itself. maybe some bugs?

There's always been a stale link or two, which was annoying to teachers...but they'd eventually find their stuff in the end.

Seems something recently/likely (with NGINX or something else recent in Raspbian??) brings 2 softlinks for each stick...perhaps related to USBx dirs never being deleted...so this growing flood...confuses everyday teachers.

look at the stick itself and I think it has a link, which is new
