The Modify and Write permissions for Ann were set to Deny when the file was in Joe's Documents folder. Explanation: If Joe used the move operation to transfer the file from his Documents folder to a folder that has been configured to give Ann full control of all files, it is most likely that Ann can't update the file because the file is now located in a different directory with different permissions. In order for Ann to be able to update the file, she would need to have write permissions to the new directory.
