You can add new special permissions to a file or folder by following these steps:
1. In Windows Explorer, right-click the file or folder you want to work with and
then select Properties.
2. In the Properties dialog box, select the Security tab and then click Advanced.

sions tab in a new dialog box.
4. Click the existing user or group whose permissions you want to remove, and
then click Remove.

Ownership Permissions
The owner of a file or a folder is the highest permission holder. Regardless of whether
the permissions on the file or folder allow the owner to open the file or folder, the
owner can always reset the permissions via the file or folder’s Properties dialog box.
The default owner of a file or a folder is the person who created the resource.
You can assign or take ownership if you have the required permissions or privileges.
Individuals with the required permissions include the owner and anyone with an
administrator account.
If you are an administrator or the current owner of a file, you can assign ownership
of a file or a folder to another user or group by completing these steps:
1. In Windows Explorer, right-click the file or folder you want to work with and
then select Properties.
2. In the Properties dialog box, select the Security tab and then click Advanced.
This opens the “Advanced Security Settings for” dialog box.
3. On the Owner tab, click Edit. This opens an editable view of the Owner tab in a
new dialog box (see Figure 11-7).
4. Click “Other users or groups” to display the Select User or Group dialog box.
5. Type the name of a user or a group account. Click Check Names and then do
one of the following:
If a single match is found for each entry, the dialog box is automatically
updated as appropriate and the entry is underlined.
If multiple matches are found, you’ll see an additional dialog box that allows
you to select the name you want to use, and then click OK.
If no matches are found, you’ve probably entered an incorrect name. Mod-
ify the name in the Name Not Found dialog box and then click Check
Names again.
