More exactly this process allows you to write to a _CD_ (http://www.processid.com/tfswctrl.exe.html#) or DVD just by dragging and dropping items on the CD / _DVD drive_ (http://www.processid.com/tfswctrl.exe.html#) , same as you would do with on a normal harddrive. You can terminate this process if you don't use this method of burning. you may have a cd or dvd drive made by hp and its part of the files used to burn a cd/dvd.....or is part of the program used by your pc for cd/dvd burning..... chuck..in ok
