ＶＰＣ的硬盘也是虚拟的，而非真实的，它对应的是真实硬盘上的一个镜像文件，你对虚拟硬盘的更改只会影响这个镜像文件，而不会同等的影响真实硬盘，当然镜像文件也是存在于真实硬盘上的，所以真实硬盘也会发生一定影响。也就是说它与真实硬盘是半隔离的。
一般情况下，这种半隔离对于ＤＯＳ应用来说，已经足够了，但是如你所说，要想实现两个系统间的文件共享，在ＤＯＳ下则需要创建共享文件夹。此时，需要首先安装ＶＰＣ的“ＤＯＳ附加模块”，这在ＶＰＣ的完整安装包中可以找到，按照其中的说明，安装FSHARE.EXE并设置其开机启动以后，便可以重新引导的ＶＰＣ的ＤＯＳ系统，然后在其“编辑－属性设置－共享文件夹”中，就可以设置所有磁盘为共享。
不过，我不建议你共享所有的磁盘。一方面为了保持系统的相对独立性，另一方面共享太多资源会产生较大的性能消耗，另外，共享所有磁盘也是没有必要的，可以把所有可能要共享的文件放在一个磁盘或目录中，然后仅仅共享这一个磁盘或目录即可。

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.
