FreeDOS is a complete operating system. For new users, we recommend installing FreeDOS in a PC emulator or "virtual machine." If you install FreeDOS directly on a computer, without using a PC emulator, you may overwrite the operating system you have now (for example, Windows.) Please be careful.
It doesn't cost anything to download and use FreeDOS. You can also share FreeDOS for others to enjoy! And you can view and edit our source code, because all FreeDOS programs are distributed under the GNU General Public License or a similar open source software license.
