What's Wrong?

Running File Read on Windows is really slow, almost unusable. Please optimize the cygpath logic! On Windows, each read operation takes about 3 seconds on average, while on Linux it's only a few hundred milliseconds! It's even slower in the VSCode extension, and there seems to be some hook script involved.

What Should Happen?

Each file read takes less than one second
