What are FastExt1.dll Error Messages?


Dynamic Link Library FastExt1.dll Errors

FastExt1.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like FastExt1.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like Setup.exe - to follow. These files were created so that multiple programs (eg. FastCopy) could share the same FastExt1.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.

Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when FastExt1.dll is attempted to be loaded either when FastCopy is starting up, or in some cases already running. Some of the most common FastExt1.dll errors include:

Your FastExt1.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with FastCopy), or deleted by a malware infection. Furthermore, FastExt1.dll file corruption could be caused from a power outage when loading FastCopy, system crash while loading FastExt1.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
