What are open source file managers in C# or Java?

Question

Java

I am looking for open source projects where you can peep well-thought-out abstractions over the file system, and in general, everything that can be related to the work of the file manager. Do not tell me?

Answer 1

go to github.com, type in the file manager search (search for repositories), select the language of interest and choose.
In general , @CAMOKPYT is right, it is the abstraction over the file system that c# / java provides you.

Answer 2

And what do you need then?
want to write your own analogue of far/total?
