What would you like to be added?

Replace filepath methods for file system operations instead of path methods.

Why is this needed?

path methods are used for url operations and unix system specific file system operations. Using path methods might cause error on windows machines. People at Milvus seems to be working on making it windows compatible. So this might be helpful.

Anything else?
