HP CD/DVD Writer – TFSWCTRL.EXE

Tfswctrl.exe is the packet writing software used to write data to your Hewlett Packard or Veritas CD or DVD Rom drives. HP and Veritas drives come with a program called "DLA" which stands for "Direct Letter Access". It allows you to write files (from Windows Explorer or any application) to a CD or DVD just as if it was a hard drive. You'll find more information at http://h10025.www1.hp.com/ewfrf/wc/genericDocument?docname=lpg40566&cc;=us&dlc;=en&lc;=en&jumpid;=reg_R1002_USEN. You'll find information on how to format a disk for DLA at http://h10025.www1.hp.com/ewfrf/wc/genericDocument?docname=c00027361&cc;=us&dlc;=en&lc;=en&jumpid;=reg_R1002_USEN.

If you have a combo CD/DVD drive, HP recommends that you leave this file in place. It will be most convenient to let it run on system startup.

Some users report that this file can cause shutdown problems on some XP systems. Earlier versions of this software aren't compatible with Windows XP SP2. You'll find an updated version at http://h10025.www1.hp.com/ewfrf/wc/genericDocument?lc=en&cc;=us&docname;=c00242757.

DLA may not be compatible with Windows Vista. Please see HP's information at http://h20219.www2.hp.com/services/cache/454779-0-0-225-121.html. You'll also want to consider running Microsoft's Vista Upgrade Advisor at http://www.microsoft.com/downloads/details.aspx?familyid=42b5ac83-c24f-4863-a389-3ffc194924f8&displaylang;=en&tm; before upgrading to Windows Vista.
