The contents of a redirection file are ignored, but its presence causes Windows to check the application directory first whenever it loads a DLL, regardless of the path specified to LoadLibrary or LoadLibraryEx. If the DLL is not found in the application directory, then these functions use their usual search order. For example, if the application c:\myapp\myapp.exe calls LoadLibrary using the following path:

c:\program files\common files\system\mydll.dll

And, if both c:\myapp\myapp.exe.local and c:\myapp\mydll.dll exist, LoadLibrary loads c:\myapp\mydll.dll. Otherwise, LoadLibrary loads c:\program files\common files\system\mydll.dll.

Alternatively, if a directory named c:\myapp\myapp.exe.local exists and contains mydll.dll, LoadLibrary loads c:\myapp\myapp.exe.local\mydll.dll.

Known DLLs cannot be redirected. For a list of known DLLs, see the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\KnownDLLs. The system uses Windows File Protection to ensure that system DLLs such as these are not updated or deleted except by operating system (OS) updates such as service packs
