Deletes a folder.
FileRemoveDir, DirName , Recurse
Name of the directory to delete, which is assumed to be in %A_WorkingDir% if an absolute path isn't specified.
If blank or omitted, it defaults to 0. Otherwise, specify one of the following numbers to indicate whether to recurse into subdirectories:
0: Do not remove files and sub-directories contained in DirName. In this case, if DirName is not empty, no action will be taken and ErrorLevel will be set to 1.
1: Remove all files and subdirectories (like the Windows command "rmdir /S").
This parameter can be an expression, even one that evaluates to 1, 0 or an empty string.
[v1.1.04+]: This command is able to throw an exception on failure. For more information, see Runtime Errors.
ErrorLevel is set to 1 if there was a problem or 0 otherwise.
