Understanding File and Folder Permissions
The basic permissions you can assign to files and folders are summarized in Table 13-3. File permissions include Full Control, Modify, Read & Execute, Read, and Write. Folder permissions include Full Control, Modify, Read & Execute, List Folder Contents, Read, and Write.
Anytime you work with file and folder permissions, you should keep the following in mind:
-
Read is the only permission needed to run scripts. Execute permission does not matter.
-
Read access is required to access a shortcut and its target.
-
Giving a user permission to write to a file but not to delete it does not prevent the user from deleting the files contents. A user can still delete the contents.
-
If a user has full control over a folder, the user can delete files in the folder regardless of the permission on the files.
