-==== Tip: Using the setgid Bit ==== 
 If you have commandline access to your server, you can use the ''setgid'' bit to retain permissions to delete files below the ''data/'' directory although they were created by the web server. On directories where the ''setgid'' bit is set, newly created files/directories belong to the same group the directory with the ''setgid'' belongs to. The following example shows how to achieve such a setup for the user ''www-data'' who belongs to the group ''foo'': If you have commandline access to your server, you can use the ''setgid'' bit to retain permissions to delete files below the ''data/'' directory although they were created by the web server.

 In order to fully retain correct permissions, you must also change [[config:dmode|dmode]] to 02775 or similar so that newly created directories will also get the ''setgid'' bit set correctly. In order to fully retain correct permissions, you must also change [[config:dmode|dmode]] to 02775 or similar so that newly created directories will also get the ''setgid'' bit set correctly.
