zamarac32 Posted May 1, 2011 Report Posted May 1, 2011 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?
DreadWingKnight Posted May 1, 2011 Report Posted May 1, 2011 If you don't also enable sparse files, then windows will cause full allocation when the first piece that completes gets written.
zamarac32 Posted May 1, 2011 Author Report Posted May 1, 2011 Does it mean, Windows will write all zeroes to the file - it would presumably take some time, but I didn't notice any lengthy HD activity at torrent download start?Regarding fragmentation, in this case NTFS would prevent it, if enough free space is available on HD?
DreadWingKnight Posted May 1, 2011 Report Posted May 1, 2011 Initial allocation is just windows writing enough information to the file table to reserve the space.
