sorrey for necro posting but i think if you want to be really safe you should enable pre alocate files in utorrent. this will allocate the space needed for the file ahead of time create a begining and endpoint to the file right off the bat and than overwrite the random data in the middle as it goes rather than making a file that grows slowly as it is works. i find this little known feature will prevent utorrent from fragmenting at all. also when defragmenting, these incomplete files will still appear as their intended size and the defragmenter should move the entire thing acordingly.

I don't usually use Pre-allocate Files feature in uTorrent, but did notice that Win7 Explorer shows the final torrent file size (a movie 1.5Gb file) as soon as the download starts. Also, I run a defragmenter after downloading torrents to check the files continuity, and it shows all large torrent files (1.5 - 3 Gb each) are NOT fragmented at all. How it can happen? Is pre-allocation hard coded now, no matter whether selected or not in uTorrent Prefs? Or NTFS has anything to do with that? I mean, torrent files are expected being heavily fragmented by the nature of torrent downloads, especially when deselecting "Pre-allocate" - am I wrong? Keeping in mind, pieces are written to disk so often.

Relevant issue would be, if one needs to defrag torrent files (movie .avi files) before burning a folder with such files onto a DVD? I didn't, but noticed a horizontal line appears on TV screen quite often, when playing a movie from DVD. It divides the screen 1/3 to 2/3. Is it related to file fragmentation, or to incorrect decoding of DivX5 by my DVD Player?

I also wonder, if burning soft like ImageBurn actually defrags the file in memory or reads it from hard drive such a way that it is burned defragmented regardless of original on HD being fragmented? Can it be? Any links explaining these topics would be appreciated.

Doesn't matter what it is, it's beyond the scope of these forums.
