Guest JW Posted August 3, 2007 Posted August 3, 2007 I found the "tip" below online (search for the first line and you'll find it). Is -b really a parameter of defrag? I can find no mention of it anywhere else. The NOTE says, XP will "run this every three days or so." What does this mean? The "-b" causes XP to run defrag every three days ("or so")? What is this? The -b parameter schedules defrag to run every 3 days (or so)? I'm supicious of the "or so." How can that be? Computers don't do things "or so." TIP----------- *Secret - Hidden Command Line Switch* Instructions - Go to "Start", "Run" and Type defrag c: -b to defragment the Boot and Application Prefetch information. Notes - Windows XP will run this automatically every three days or so, during system idle periods. BootVis will evoke this when you run the "Optimize System" function. There is no need to manually run this unless you wish to immediately optimize a newly installed application's load time.
Guest Bob I Posted August 3, 2007 Posted August 3, 2007 Re: defrag c: -b<--?? The "or so" is the Authors best guess as to what the time frame is. In reality, does it matter if it's 3 days, 72 hours, or 7 times a fortnight?

Guest JW Posted August 4, 2007 Posted August 4, 2007 Re: defrag c: -b<--?? Bob I, My question is does anyone know if the -b option loads defrag in some way that causes it to run on a scheduled basis?

JW <JW@discussions.microsoft.com> wrote: > Bob I, > My question is does anyone know if the -b option loads defrag in some way > that causes it to run on a scheduled basis? no, it just tells it to do the "boot time optimize" defrag. and yes the -b switch is documented. this same cmd line is kicked off periodically when the machine is idle. that's the "every day or so" talked about. this boot optimize function relys upon info in the \windows\prefetch folder, specifically the layout.ini file. It too is rebuilt by the above periodic task, and then the defrag is initiated; it takes about 60 secs to complete, most people never notice it take place since it happens when the machine is idle (screen saver is up). TweakUI does have a check box where you can disable this defrag if you wish; some defraggers turn it off too, as they do the same thing, only better, and disable xp from doing it and messing up what they already did. google around, there's info re: this out there...
Guest Bob I Posted August 6, 2007 Posted August 6, 2007 Re: defrag c: -b<--?? No, from what I understand the -b option simply allows a user to "force" the "boot optimization" on command, rather than waiting for the system to perform it during idle time.
