Command to Delete All Files Permanently with No Prompt

What parameters with the del command can I use to delete a folder, all of it's contents, for all file types (read-only, those with missing permissions, etc), permanently, and without a prompt to select yes or no.

Is this sufficient?

Del "Z:\FolderName" /f

/f is for force deleting of read-only files.

/q is for quiet mode, i.e., do not ask if ok to delete on global wildcard.

if you dont have permissions to files it wont work still of course, will need to push permissions down and/or take ownership as usual.
