I know there are many such softwares, and I've used some in the past whose names I don't remember now, so can anyone please recommend a preferably free software that allows you to see how much data has been uploaded/downloaded in a particular session and daily and so on. Please don't say something like the ISP's usage site. I need something that tells me how much data has passed starting from a certain time, and also how much data is passing through at a particular time (especially useful when you're using a site with heavy graphics).Vista and 7 have widgets that allow you to do this, but I'm using XP.
