What is TeraCopyExt.dll?

The genuine TeraCopyExt.dll file is a software component of TeraCopy by Code Sector.
TeraCopyExt.dll is a DLL (Dynamic Link Library) file that is associated with TeraCopy, a program designed to copy and move files at the maximum possible speed. DLL files store data, code and resources needed by one or more programs in order to function correctly. This file is not a critical Windows component and should be removed if known to cause problems. TeraCopy uses dynamically adjusted buffers to reduce the seek times and asynchronous copying to speed up the file transfer between two physical hard drives. The program also features the ability to pause transfers and resume them at a later time. During a copy error, TeraCopy will repeatedly try to recover, however, if it cannot, it will simply skip the file, and not simply terminate the whole transfer. The files which failed to transfer are displayed in a list in the end, allowing the user to fix the problem and recopy only the problematic files. TeraCopy integrates with the Windows shell, thereby completely replacing the default Explorer 'copy' and 'move' functions.

Best practices for resolving TeraCopyExt issues

A clean and tidy computer is the key requirement for avoiding problems with TeraCopyExt. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

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 resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
