Need Syntax Help w Batch File Script - it deletes junk files after Win Cleanup is Done

So I put this script on over 100 computers, ran them for months. Worked fabulous! Often cleared an extra 1 GB of junk files right after I was done with regular MS cleanup. If I ran it again by accident a second time, still maintained integrity, just echoing 'files not found.'

One day I shared this with a friend overseas. He ran it as I watched.. and it began to delete his entire system32 folder! And a few weeks later, it happened again, as I was remotely running it on PC I was cleaning up for a client. (file script was already hosted on the target pc)

Since batch files drop to C:/windows/system32 by default when it runs in PowerShell, I know that for some reason my script syntax on the 'delete commands' are wrong.

Why it works 99% of the time is still a mystery, though
