Controlled Copy (or CCopy, or CC) was an advanced file copier I built back in the early 90s. I’ve stopped development on it many years ago, but apparently there’s still quite a few people using it. CCopy was shareware and during the years many people and institutions did register. However, since development has stopped and CCopy (and DOS altogether) has become a fringe area in my life, I released CCopy as freeware. There’s the historical CCopy site which might be of sentimental value to somebody, but that’s it, I guess.
You can download the free registered version of CCopy and use it for your own personal use for free. Have fun!
