Windows file explorer shows some entries that are not accessible from the file system (ie java file read/write) For example, the ‘EPIX’ entry under ‘This PC’ (a smart watch connected by USB) behaves like a USB file system in file explorer. But doesn’t appear in the ‘/’ root directory from java/python/etc programming languages. How can a program access the files under ‘EPIX’ as file explorer shows?

Notice I said under ‘/’, showing that I’m unix sort of person who expects EVERYTHING to show up in THE filesystem somewhere. Is there some way I can these ‘devices’ or pseudo file objects, like open a USB device by some name?
