Question relating to streaming

There is a folder definately where the video/movie file is being stored in my computer temporarily when a streming of video file is going on. Can you tell me what is the exact directory of the temporary folder?
After complete streaming of a video file, I found that space in my C:\ drive has decreased exactly to the size of the video file. So, does anyone of you guys know which folder/directory it is being stored.
Thanks!

Yes, I assume you're working on Windows because you're talking about a C:\ drive, so your video file should be in the Windows temporary folder (environment variable named %Temp% --> C:\Documents and Settings\<Username>\Local Settings\Temp).

Good luck ;)
