temporary downloading from net

Question for the real techie: When a file (PDF) or image (jpg, gif, etc.) is downloaded from a website, you know, when the status bar is showing it, when you are only temporarily viewing this thing (file or image) and not saving it, is this downloaded ONLY to RAM and then only to hard drive if saved in My documents or somewhere like that? In other words, just viewing this from a website and then moving on to something else. It is only downloaded to RAM and not the harddrive, right? No permanent file is saved after power turned off in this case, unless you physically SAVE the file onto the HD. ps I already know about Internet options and history and cookies, etc. Thanks

 

A download of say, a .pdf, will go into the temp internet folder and stay there until emptied.

RIGHT click on the IE icon on the Desktop, and choose Properties. Make sure the Temp Internet Folder size is no higher than 80mgs. This is good for security reasons. From there you can empty your Temp Internet folder and History. So, when you are downloading something, that doesn't give you a choice as to where to save it, then it is in your Tempoary Internet folder.
