This option allows a user to delete a directory containing a read-only file. By default, DOS and Windows will not allow such an operation. You probably will want to leave this option turned off unless a program needs this capability; many Windows users would be appalled to find that they'd accidentally deleted a file which they had set read-only. In fact, even the Unix
rm
command will ask users if they really want to override the protection and delete read-only files. It's a good idea to have Samba be at least as cautious.
