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