Question Same Filenames but Different Files?

I have been using XoloX for about 1 week. It works fine on my P4 machine connecting via broadband. I have downloaded many files apparently successfully.
My question is this: When one selects a file for download eg. "filename.exe" and during download other users have this same file name listed and XoloX goes from one to the other how does it know it is actually the exact same file? In other words if several people share the same file name how does the XoloX program know if they are indeed the same exact file or different files with the same name?
How does Xolox tell if the files are exactly the same: by name, by size, by date or by what method?
Sorry I really asked 3 questions in order to ask 1.
I'm just curious and it seems a mystery to how Xolox would know not to switch to another same file name when the file could be different and just named the same by various users.
Thanks to anyone who posts the answer.
