In most circumstances, we do not recommend the use of virtual disk volumes. Instead, the default procedure is to create a Linux file when a DOS or Windows application creates a file. This procedure provides an easy-to-use and easy-to-understand situation where one DOS file corresponds to one Linux file.
One possible use for virtual disk volumes is to support applications that operate on DOS volumes at the block level. These applications will not work on the Linux file system, but may work as intended on a virtual disk volume.
You must attach a virtual disk volume to your DOS or Windows session before you can use it. See Help for Drives & Filesystem View of Personal Win4Lin Session Configuration for instructions on attaching a virtual disk volume to a DOS or Windows session.
