China DOS Union

I'm using the Windows XP operating system. I installed Virtual PC on my computer,
and then I used this thing to install DOS,
but why can't this thing manage the entire computer's hard disk? I have four disks: C, D, E, F. When I use the dir command in DOS to display the C drive, it only shows the file directory under DOS,
I just want to use a virtual PC to install a dual system, so that I can develop C language under DOS,
but it just doesn't work,
Which expert can tell me? Little brother is anxious.

Manage the entire hard disk? Try the FDISK command!

Re: lyl_cny:

The hard disk of VPC is also virtual, not real. It corresponds to an image file on the real hard disk. Changes you make to the virtual hard disk will only affect this image file, and will not equally affect the real hard disk. Of course, the image file also exists on the real hard disk, so the real hard disk will also be affected to a certain extent. That is to say, it is semi-isolated from the real hard disk.

In general, this semi-isolation is sufficient for DOS applications. But as you said, to achieve file sharing between two systems, you need to create a shared folder under DOS. At this time, you need to first install VPC's "DOS Add-on Module", which can be found in the full installation package of VPC. Follow the instructions in it to install FSHARE.EXE and set it to start at boot, then you can reboot the VPC's DOS system, and then in its "Edit - Property Settings - Shared Folders", you can set all disks as shared.

However, I do not recommend that you share all disks. On the one hand, to maintain the relative independence of the system. On the other hand, sharing too many resources will cause greater performance consumption. Also, there is no need to share all disks. You can put all the files that may need to be shared in one disk or directory, and then only share this one disk or directory.
