Drive compression was also aquired, as was much that went into windows.
Actually, drive compression was stolen from Stack-It, (which I bought just prior to MSDOS 6.0, and immediately saw that both Stack-It and drive compression used all the same commands), a company they then bought in order to get out of the law suit. Most of what MS added to MSDOS in the early days was the result of buying the competition or stealing from them.
