I already posted this in the WinME forum without a whole lot of response. May you can provide additional insight. I know what Applog and TaskMon do: “help” defragmenters do a “better” job. But, after doing a lot of reading and Web searching, I think the Applog should be deleted at least occasionally, if not regularly. There have been some reports of Applog being as big as 30 MB, and a corrupted applog resulting in longer boot times. “With short seek times and high transfer rates of today’s hard drives, [Applog and TaskMon] are probably superfluous.” http://www2.whidbey.net/djdenham/Uncheck.htm “This specialized processing reduces the time required to launch certain programs, but you may prefer to trade that speed for disk space. You’re perfectly free to delete the entire contents of this folder.” http://pcmag.com/print_article/0,3048,a%253D17516,00.asp Give me some reasons NOT to delete Applog, based on your EXPERIENCE, not textbook, hypothetical reasons. Thanks! =============================================

The sole purpose of the files found in \Applog, are to allow Windows Defrag and other defrag programs that use \applog (like Speedisk), to arrange the clusters of these programs, in such a way as to speed their initiation. So, the only reason NOT to delete these files, is to continue to allow defrag to do this optimization.

ya and that be da tooth!

I can think of no reasons. It will rebuild again anyway. I tend to agree with the quotes you mention. Incorporated into a 'weekly' maintenance plan would be good. Deleting everything everytime the PC starts is somewhat self defeating. The only reason I can see for deleting everything that is not needed would be to gain some speed. If the operation is run at start up then this will take time. Which takes longer? What would be good is a batch file that could be set to run weekly rather than at every start up. Speed gains at both ends. Bryan

I think you either want to keep the files,or delete the files (and disable taskmon). Deleting them on a regular basis defeats the purpose, since each start is logged and taken into account in order to find the optimal start sequence over time. The only time I would delete (and continue to run Taskmon) would be if I had a defrag problem (Defrag0205 OR defrag was hanging at 10%).
