UPLOADS: a simple question
 

Guys, I realize this is probably a silly question but it's been bugging me and I couldn't find the answer to it. So when I'm watching the shared files in my library, under the Uploads tab I have X/Y, where x and y are numbers. So something like Uploads 3/7, or something like that (mostly 0/1). I was wondering what do X and Y mean?
Thanks for your time!
