When you create a shared folder it is visible to all other
users. In other words, when a user browses the network in Windows
Vista, they will be able to see that you have a shared folder
created on your computer. Here is a quick and easy way of making a
folder hidden so user will not be able to see it when they browse
the network.
1. Right click the folder in Windows Explorer and click
Properties.
2. Click the Sharing tab.
3. Click the Advanced Sharing button.
4. Click the Share this folder option.
5. Type in a name for the shared folder. Append a $ character to
the end of the share name.
6. Click OK.
By appending a dollar sign to the end of the share name, you create
a hidden share. In other words, the folder is accessible to users
on the network if they know it exists. It will not be visible when
users browse the network. To access the folder, users have to type
in the path and the share name. For example,
\\MyComputer\SharedFolder$. If you omit the dollar sign character
at the end of the share name when typing in the path, the resource
will not be found
