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.
This parameter determines whether to recurse into subdirectories. If omitted, it defaults to 0 (false). Specify one of the following values:
0 (false): 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 (true): Remove all files and subdirectories (like the Windows command "rmdir /S").
This parameter can be an expression, even one that evalutes to true or false (since true and false are stored internally as 1 and 0).
[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.
