16 | Abstract:\r | |
17 | \r | |
18 | Produce Simple File System abstractions for directories on your PC using Win32 APIs.\r | |
19 | The configuration of what devices to mount or emulate comes from NT\r | |
20 | environment variables. The variables must be visible to the Microsoft*\r | |
21 | Developer Studio for them to work.\r | |
