It is a step away from a classic concept of engine/lib/framework, the stable blackbox with API you call into.

One could modify this to use a PC emulator like PCjs  and then run real DOS under it, and then really format your virtual C drive. (FreeDOS or MS-DOS 2.x could be run entirely legally; running newer versions of MS-DOS might not technically be legal but I doubt Microsoft would do anything about it.)
(iDOS 2 doesn’t support the smart keyboard folio.)
Double commander has been produced which also gives total commander plugins comparability across all platforms!
