Volkov Commander is purely written in assembly language and is very small (less than 100 KB) and fast.
It is a pure DOS application, so it doesn't support special features of Windows 9x like long filenames.
"Beta version (4.99.xx), of course, can be tested for free, because in this stadium of development it does not yet represent a complete program."
Rumours about existing Version 5 of Volkov Commander: VC 4.99.08 is included within Ultimate Boot CD (UBCD) v3.4, as part of the general FreeDOS base package.
Volkov Commander is included in the NwDsk DOS network boot disk.
