Using the dot prefix for folder names is pretty standard fare in the Unix/GNU world. The folder is hidden and forgotten, but perfectly accessible if you wish to do something with it. I demonstrate with the typical location of a Betaville cache folder:

rm -R ~/.betaville/cache

Cool! I just deleted my cache folder. Now let’s try a similar feat from the Windows command line:

rd %USERPROFILE%\.betaville\cache /s /q

Uh-oh, The folder couldn’t be found. What gives? After too much guesswork, wrapping the path in quotes seemed to do the trick and I was able to get on with my day. Such is life in Windows.

rd "%USERPROFILE%\.betaville\cache" /s /q
