    ok, differant advice for vista then xp;

    in vista, "system managed pagefile" means the system is going to delete the pagefile and recreate each time you boot, it's not going to be available until much later in the boot process.

    unless you have some worries about someone stealing your hardrive to get access to data in your pagefile, you don't need this "security safeguard"

    so the os creates the pagefile later on in the boot and programs like pd can't find a pagefile on bootime defrag because the pagefile isn't there yet

    therefore, for vista, instead of system managed pagefile, use your amount of ram x 1.5 for the minumum, (up to 2 gigs, no need to exceed 2 gigs for initial minimum no matter how much memory you have unless the pagefile is expanding from your use, if it's expanding set the initial minimum to 25% more then the expanded size)

    go to whatever you want for the maximum, I think there's a limit of 10 gigs but I don't know in vista.

    whatever maximum you choose, the os only expands pagefile if needed, and then only expands in small pieces which are discarded on the next boot.

    bottom line, system managed pagefile for vista is counter productive, set it manually with a reasonable initial minimum and a huge maximum

    in xp it would make a min pagefile of 2gb in vista im sitting on 3.29GB, so if like me you have 3GB your saying have a min of 2gb and max of 6gb, as i was always told to use 2x ram, unless space was limited then use 1.5x, that sound about right ?

    just checking that thats right :) , i had noticed a few times that PD said there was no active pagefile when i had it set to do an offline defrag, thought it was strange

    that's why pd couldn't find it, it was system managed

    go into the applet and click custom size, set your initial minumum to what the system set it, set the maximum to whatever you want, and pd will have no trouble defragging the file

    the first time pd defrags the file if your drive is full it will try to put at the most optimum spot, that might take a while, it won't take a any time at all after that because the file won't get fragmented once it's contiguous

    therefore, after the first defrag I suggest excluding the pagefile for future boot time defrags
