By default, the letters for drives in Windows Explorer are shown. For example, your main Windows 7 hard drive is most likely C:, your DVD drive may be D: and other drives and partitions and removable media, such as USB flash drives, have their own drive letters.

If you can tell which drive is which by each drive’s volume name and/or media type, and you don’t want to see the drive letters in Explorer, you can hide them.

Click the Start button, enter “folder options” in the Search box, and press Enter, or click the Folder Options link.

The Folder Options dialog box displays. To hide the drive letters in the right pane in Windows Explorer, click the View tab, and select the Show drive letters check box so there is NO check mark in the box. To show the letters again, simply select the check box so there is a check mark in it.

When you hide the drive letters in Windows Explorer, they are hidden in the right pane, but they still display in the Computer list in the Navigation pane, as shown below.
