If like me you are one of the older guys reading this, then you would probably have fingered the old (DOS) DELTREE as the command to use, but seeing as this was technically replaced ages ago, the correct answer is in fact RMDIR, which is responsible for removing a directory (and with switches, an entire directory tree, folders, files and all!).
Given a folder called ‘annoying’, you can banish it by running:
Of course this will fail if ‘annoying’ isn’t empty. To get around this and delete the entire directory tree, in other words a recursive file and folder delete, we employ the /s switch:
rmdir /s c:\annoying
And if we don’t want to be prompted or bothered again by what is about to happen, we force the command into quiet mode with the /q switch:
rmdir /s /q c:\annoying
