Here's a quick-'n-dirty tool for easy, automated file transfers from a Windows host to a running machine in PCem/86Box (especially if it runs DOS). No need to shut down/restart the emulator, to set up virtual networking, or to manually create/mount/eject floppy disk images.

It uses the disk-image approach, but does it transparently, in one click. Useful if you tend to update sets of files very often - for example, if you do your DOS programming with native Windows tools, and switch to the emulator for quick testing and debugging.

That was my own motivation for making it: these emulators don't have DOSBox's native filesystem integration, and you can't update the HDD image without shutting down the guest machine first. ... Posted by VileR Apr 15, 2020

I find this interesting because it (presumably) re-uses the DOS support for removable media (ie diskettes) to allow access to a completely rewritten disk image.

Of course, dosemu2 provides access to (Linux) host directories as DOS redirector drives using its mfs redirector, which is similar to "DOSBox's native filesystem integration" except it works with any sufficiently compatible 86-DOS.
