GMail Drive is a free namespace extension ('add-on') for Microsoft Windows. It allows a user to access a virtual drive stored in a Gmail e-mail account by causing the contents of the Gmail account appear as a new network share on the user's workstation. In order to use this add-on, a user needs a Gmail e-mail account. The add-on enables a user to use the normal Windows desktop file copy and paste commands to transfer files to and from the Gmail account as if it were a drive on the computer.

GMail Drive uses the inbox of the users GMail account to store files. Consequently, restrictions on the GMail service are also enforced when using GMail. For example, users are not able to upload files greater than 10 MB. GMail also prevents users from transferring certain file types, such as an executable or zip archive. Some users overcome this restriction by renaming the file extension.
