I checked my Temporary Internet Files folder, and made everything visible, but all I found was the tiny pictures which make up websites, like this one right now. When I watch a video on the internet, where on my computer is that data stored?
When you watch a video for example on Youtube the information for that video is simply being "transferred" to your computer from the websites server.
the temp internet files just show some of the information of the web page you visited.
temporary internet files usually.. unless you actually "download" the file
search your temporary internet file folder.. in fact all the windows temp folders.. for large file size.. say watch a 10 MEG file.. then do a seearch on those folders for any file over 9 MEG.. find it that way.. temp files wont always have the "actual" filename you expect. once you find where they go with a large file.. you can prob find where the smaller ones are going too.
