What permissions does Windows require in order to rename a file?
Windows treats a file renaming operation as a deletion of the file and creation of a new file with the new name. Therefore, you must have either the Delete permission on the file itself or the Delete Subfolders and Files permission on the folder that contains the file. You must also have Write Data permission on the folder because of the new-file creation. In addition to these permissions, the ren command requires Read Attributes permission and Synchronize permission to both the folder and the actual file and the List Directory permission to the folder. These permissions allow the ren command to check for the existence of the file and verify that the file's attributes (e.g., the Read Only attribute) don't prevent the rename.
