NTFSLib.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like NTFSLib.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like iscsicli.exe - to follow. These files were created so that multiple programs (eg. EaseUS Disk Copy) could share the same NTFSLib.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 NTFSLib.dll is attempted to be loaded either when EaseUS Disk Copy is starting up, or in some cases already running. Some of the most common NTFSLib.dll errors include:
- Access Violation at address - NTFSLib.dll.
- NTFSLib.dll could not be found.
- Cannot find C:\Program Files (x86)\EaseUS\Disk Copy\BUILDPE\EaseUS\dc\bin\x64\NTFSLib.dll.
- Cannot register NTFSLib.dll.
- Cannot start EaseUS Disk Copy. A required component is missing: NTFSLib.dll. Please install EaseUS Disk Copy again.
- Failed to load NTFSLib.dll.
- The application has failed to start because NTFSLib.dll was not found.
- The file NTFSLib.dll is missing or corrupt.
- This application failed to start because NTFSLib.dll was not found. Re-installing the application may fix this problem.
Your NTFSLib.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with EaseUS Disk Copy), or deleted by a malware infection. Furthermore, NTFSLib.dll file corruption could be caused from a power outage when loading EaseUS Disk Copy, system crash while loading NTFSLib.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.
