I can also do the floppy drive to wake Subst.exe

Once upon a time, the floppy disk was reused by every computer enthusiast, so many brand-name manufacturers have started to try to cancel the floppy drive in the new model, and replace it with the USB flash memory, especially the notebook computer.

However, the lack of a floppy drive this old friend, sometimes really inconvenient. Some commercial software in the installation or update will require to read from the floppy disk installation information, such as the rising anti-virus software installation of the protocol disk, of course, there are many other software. At this point we can not go to the floppy disk to buy a new floppy drive, then try the following method.

The first step: let Subst.exe glow Youth

Subst.exe is a less commonly used DOS command, its location is hidden under \windows\command\ (for Windows 9x/me System), and in the case of Windows 2000/XP, it should be hidden under \windows\system32\.

Subst.exe's Chinese name is "assign a drive letter to a directory", which features a disk drive letter instead of the path name to associate the drive letter with the specified subdirectory path, and the command format is simple: Subst.exe [Driver1: [Driver2:] path]

The "Driverl" is the virtual drive letter that specifies the path to assign, and "Driver2 path" specifies the physical drive and the path to be assigned to the virtual drive.

Step Two: Use Subst.exe virtual floppy drive

Before installing the rising anti-virus software, you can copy all the files in a disk to a folder in this computer by other means (such as LAN, Mail, shared files), for example, under D:\temp. Next, type the command "subst (space) A: (space) D:\temp" below the command Prompt window, and then use the "dir A:" command to see the list of files here. In this way, we can according to this method will D:\temp folder virtual into a disk, rising anti-virus software installation can be successfully completed.

When we virtual floppy drive, you will find that the floppy drive icon has become the hard disk icon, of course, double-click Open is the contents of the D:\Temp folder.

Note: Remember that after the end of the work must promptly delete this virtual out of a disk, otherwise not normal use of the original physical a disk yo. To remove this virtual optical drive, just execute the "subst (space) A: (space)/d (It is a delete command, not the D disk) command."

Some software can only run on floppy disks, a special design by software developers, primarily to prevent illegal copying. However, we can use the Hd-copy tool to make a floppy disk extension of the image of an IMG file in a folder on the hard disk, and then using the Imgdrive, Undisk and other tools to expand the image file, so that you can create a virtual floppy disk, It's natural to work, but if it's encrypted, it's not going to work this way.
