If you often use a shared folder on someone else's computer, why take the time to drill down through My Network Places to locate the computer and the folder on it. It's much more convenient to map the folder to a drive letter - where it's easy to locate files using File Open dialogue boxes or switch to the drive in Explorer. To map a shared resource to a drive letter, open Windows Explorer and select Tools-Map Network Drive. Select an open drive letter in the Drive area; click the Browse button next to the Folder field to find the shared folder. Then click OK and Finish.
