I noticed similar behaviour with Kazaa, e.g. source code snippets in partially downloaded files. Since it doesn't make much sense to interleave personal data with stuff you download I've come up with the following explanation (much guesswork): Kazaa (and probably Grokster too) can download parts of files simultaneously from different sources. In order to do this it maps the local destination file to memory (using MapViewOfFile() or a similar function) and writes the downloaded file snippets at the offset in memory they belong. Until the entire file is downloaded there are parts that have never been written to by the application. Windows seems not zero those parts and they still contain old data from physical RAM, the swapfile or the disk. The .dbb files you mention are probably databases which are also good candidates for file mapping. > I don't know if my firewall stopped > them from getting this information, but it is not > something you want to see. Time for Netscape. I don't think the software attempted to send anything. It just failed to zero the file before using it which isn't much of a problem and would've just decreased performance. regards Markus
