public class WindowsDirectory
extends FSDirectory

Native Directory implementation for Microsoft Windows.

Steps:

1. Compile the source code to create WindowsDirectory.dll:

   c:\mingw\bin\g++ -Wall -D_JNI_IMPLEMENTATION_ -Wl,--kill-at -I"%JAVA_HOME%\include" -I"%JAVA_HOME%\include\win32" -static-libgcc -static-libstdc++ -shared WindowsDirectory.cpp -o WindowsDirectory.dll

   For 64-bit JREs, use mingw64, with the -m64 option.
2. Put WindowsDirectory.dll into some directory in your windows PATH
3. Open indexes with WindowsDirectory and use it.
