Tfswctrl.exe belongs to the Drive Letter Access (DLA) component, which is part of the DirectCD software. DirectCD is a Packet Writing software manufactured by HP, VERITAS and Sonic Solutions. The process allows a user to write data on CDs or DVDs by using Windows Explorer. This process is not an essential system process, but it should not be terminated unless you suspect that it is causing errors and problems on your computer.
The Tfswctrl.exe process runs at system startup and enables the DLA component of program writing software to work properly. This is an essential process if you are not using the usual CD/DVD writing software such as Roxio or Nero. Tfswctrl.exe basically controls the readability of combo disk drivers. If you don’t have this file on your system, you may still be able to write disks, but will not be able to read from them.
By default, the tfswctrl .exe file is located in the C:\WINDOWS\system32\dla\ folder. You will find entries related to it in the following locations within the Windows registry:

Tfswctrl .exe Errors and Fixes
You may receive a Tfswctrl .exe error message if the DLA software becomes corrupt or incompatible with other applications such as Packet Writing Utilities on your system. For example, the DLA may generate the following error when you install Windows XP Service Pack 2 on your computer:
“Direct Access Component has encountered a problem and needs to close”
This error is generated due to an incompatibility between Windows XP Service Pack 2 and earlier versions of DLA or the Tfswctrl .exe process.
You can solve this problem by installing an updated version of the DLA software. You can download the updates from your computer manufacturer’s website.
If updating your DLA does not resolve the Tfswctrl .exe application error, then next thing you can do is to disable the program. You can disable the program by using the following method:
- Open the Start menu, select Run.
- Type msconfig in the Open box and click OK to launch the System Configuration Utility.
- On the Startup tab, search for the tfswctrl.exe or tfswctrl process and then clear its checkbox
- Click Apply and Close to save your settings and exit the dialog box.
- Choose Restart when asked to reboot your PC.
In case the tfswctrl.exe error still remains, then the only option you have left is to remove DLA completely from your system. To uninstall the software, you may use the Windows Add or Remove Programs utility. However, if you are facing problems, you may seek the help of a reliable third-party program uninstaller tool, such as Perfect Uninstaller. Also, after performing the installation clean up your registry by using an efficient registry tool, such as RegServe, to ensure complete software removal by getting rid of any left-behind orphaned entries related to the program.
