The Co Systems programs primarily use the Topspeed data file drivers which are a proprietary driver of  Softvelocity.  They support many file driver functions are extremely reliable in multi-user network  applications.

At CO Systems we have been using the same data files for the past 12 years which have been updated  over 1000 times and used by up to 35 used directly on the local are network and on a Citrix server from  user homes and from a remote office of 10 users.  

The program makes extensive use of Views, which reside in memory when browsing files.  Consequently  network traffic is minimized and potential for file damage is also reduced.  

The use of small UPS battery backups is vital to protecting data on all workstation and network server pc's.
