Changing a File or a Directory Properties

If you are setting permissions for a file, mark the relevant checkboxes in the Permissions section to set a file owner (both a user and a group) and for other users and groups. In Ownership section, you can change the file owner and/or group (select a new owner and/or a group from Owner and Group drop-down menus respectively. For executable files, you can change the identity of the user running the file to the owner of the file so that the user can perform privileged operations (mark the Execute as user checkbox); and you can also put files created in the directory into the same group as the directory, no matter what group the user who creates them is in (mark the Execute as group checkbox);

If you are setting permissions for a directory, mark the relevant checkboxes in Permissions section to set permissions for a directory owner (both a user and a group) and for other users and groups. You can prevent users from removing or renaming a file in a directory unless they own the file or the directory; this is called the restriction deletion flag for the directory (mark the Only owners can delete files checkbox). In Ownership section, you can reassign a directory owner and set the execution attribute: select an owner user and/or a group from drop-down menu. You can also put files created in the directory into the same group as the directory, no matter what group the user who creates them is in (mark the Files inherit group checkbox). Finally, you can make one more general setting: mark the Apply changes for files and directories recursively checkbox to automatically apply changes made for a given directory to all files and subdirectories in this directory.
