i'm a pretty casual user of file sharing programs and am not too knowlegable of the inner workings of bit torrent but the last two files i downloaded contained a file named 'system information' which made me a bit paranoid as when i opened it it seemed to be details of my computer. obviously this becomes available to others once i start distributing it. should i worry about this? the thing that made me even more paranoid was when i tried to delete this file it said i couldnt cos it was being used by someone else. any words of wisdom much appreciated!
