If in Windows 7 or Vista, while working with a particular file or folder, Windows throws up an error message saying that You do not have permission to do something, then you need to take full control of the file or folder.
Generally speaking, file / folder permissions determine whether you can access, read, write, modify a file or folder.
The Error messages you get may be any of the following types:
* You don’t have read or write permission to the specified path
* You don’t have permission to modify the file or folder
* You need permission to perform this action
