cddt:
Windows 11 (work PC).
"Extract all..." to decompress an archive which contains exactly one text file. Somehow Windows is now interpreting the single text file as separate files per line, so it's choking on "copying 55,328,519 items".
Absolutely crazy how far this OS has regressed.
Update: 7-zip completed this process in 15 seconds, resulting in one correct file. I cancelled the Windows extraction process after an hour, during which it had created 2,179,781 files. Insanity.
