Standard program used by DirectCD. Drive Letter Access Component ( from properties ) version ( Windows XP on a Toshiba Laptop )
Windows Explorer stops working. Can use and open files directly with the associated application but can't see the files existing in the hard drive.
  Mr. A.  
says it cannot start, infected by w32/blaster.worm. won't let ANY program stay open
Had many problems. Crashes , super slow , programs nonfunction or malfunction , startup/shutdown glitches. I think a virus or trojan messed up tfswctrl.exe. I removed and reinstalled sonic. Seems all fixed.
Causes problem whenever I shut down my hp notebook. In process explorer it is even not possible to 'verify' this shit. That's the kind of stuff I would like to clean off if I didn't have to write a CD once every two years.
Along with Norton internet security packages 2009 and 2010, it will cause blue screen of death. when I completely remove all norton software, it works fine, but then I have no internet security. if i need to read/write cd's norton gotta go, otherwise this utility gotta go. combination of two keeps on crashing my windows xp professional.
when I try to suspend it, it unsuspends itself! it also will not let me kill it. I removed it from startup in the registry and my machine runs a whole lot faster
Part of Sonic's Roxio Record Now Direct CD (DVD & CD Burner program); Can be corrupted, can be exploited; Usually stored in System32\dla\ here .exe; Required for certain burning hardware; Required at Startup for CD burning hardware/software;

Best practices for resolving tfswctrl issues

A clean and tidy computer is the key requirement for avoiding problems with tfswctrl.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem.
