Question

I am wondering how to get the relative path name? Any existing library can help this?

c:\123
c:\123\1234\zaq\erf

I would like to get something like 123/1234/zaq/erf

Use the relativize() method in the URI class. Construct a URI from the base file path and then relativize your absolute file path.

String s = new File("c:\\123").toURI().relativize(new File("c:\\123\\1234\\zaq\\erf").toURI()).getPath();
