You cannot move the pagefile under Windows. When you disable and reenable the pagefile, Windows will put it at a random location (usually near the beginning of the disk, if enough space is available, I guess)

The AddGap(UntilPercentageOfVolumeMultiple(1)) statement from Zone 3 is missing in the second script. You also have to change the '1' to '5' to make a 5% Gap. The gap size in zone 2 is also different.
Keep in mind that SortByNewestDate(Ascending) also takes the last accessed date into account, so the sorting may change every day. To make a single block I would recommend SortByCreationDate(Ascending) to put newest files at the end. More efficient, but may leave small gaps due to unmovable files, would be FastFill(WithShuffling).

You can do this in one VolumeSelect: Remove the first VolumeSelect and put the MakeGap(PercentageOfVolume(100)) statement after FileEnd of the second VolumeSelect. This will move all *.exe-files down and everything else up.
Btw. the MoveDownFill() statement does nothing, because SortByName() already moved everything down without leaving gaps.

MyDefrag v4 Forum / Questions and help / Re: disable or enable the "Optimize harddisk when idle"
|

In any way a suggest to everyone to disable( set to zero) HKEY_LOCAL_MACHINE\SYSTEM\CurrentContolSet\Control \Filesystem\NtfsDisableLastAccessUpdate  I would suggest to turn this feature off (= set to 1, standard in Vista/7), because it will decrease the overall performance. MyDefrag will only make use this feature if it is enabled. You should not confuse this with "frequently accessed files". Also note this item in the LastAccess description: Some improperly programmed utilities cause a change in the last access time of all items on the disk when they scan the disk. Examples are virus scanners, backup programs, text indexers.

MyDefrag v4 Forum / Requests for new features / Re: SSD disk support

You question is already answered in the article you posted. The problem is that some SSDs don't support this feature: Basically, Windows 7 will send TRIM commands down the storage chain, but it's up to the drive to accept the commands and utilize them. In order for TRIM to work, you not only need Windows 7, but you'll need a solid state hard disk which has support for TRIM via its Firmware.

The "import list from boot optimize"... doesn't that only apply on boot partitions?
XP makes entries for files on other partitions in the layout.ini. Win7 only for the system partition. I'm not sure about Vista but I guess it's the same like 7.

This should do the trick: VolumeSelect Name("D:") VolumeActions
/* Move everything except special folders down */ FileSelect all & not ( DirectoryName("Lataukset") or DirectoryName("Fraps") or DirectoryName("Anime") ) FileActions FastFill() FileEnd /* Move everything not yet processed up */ MakeGap(PercentageOfVolume(100))
VolumeEnd

Quote and is it okay to enable the boot optimize function of microsoft and use this to import it like this? Yes. The function is already used in the standard MyDefrag scripts.
hm so i think the boot optimation from windows is fine if its enabled Which boot optimization are you talking about? Like jonib said, there is also a function called boot optimization where Windows will place files by itself at a random location to make booting faster. Of course this will heavily mess with the optimization of the MyDefrag scripts. If you don't defrag daily, after a week the disk will look like as if it was never optimized. The function can be disabled here: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction] "Enable"="N" The ImportListFromBootOptimization() loads a list which is generated by super/prefetch and has nothing to the with the above setting.

MyDefragGUI uses a different statement to create gaps.
MyDefrag: AddGap(UntilPercentageOfVolumeMultiple(0.01)) (first gap) and AddGap(UntilPercentageOfVolumeMultiple(1)) (other gaps) MyDefragGUI: AddGap(PercentageOfVolume(1)) (for all gaps, can be adjusted in the GUI)
You can find the generated script in the folder "programs" in the folder you installed MyDefragGUI.
