MyDefrag (formerly JkDefrag) 4.0

MyDefrag (formerly JkDefrag) is a disk defragmenter and optimizer for Windows. Completely automatic and very easy to use, fast, low overhead, with several optimization strategies, and can handle floppies, USB disks, memory sticks, and anything else that looks like a disk to Windows.

Changes

- Deleted the SetPalette() setting and added the SetColor() and SetFileColor() settings

- Added Estonian translation

- Added Russian translation

- The "$BadClus:$Bad:$DATA" file on NTFS disks is no longer listed in the logfile in the "These items could not be moved", "These items are fragmented", and "The 25 largest items on disk" lists

- Fixed a bug in the graphics code for drawing files on the diskmap. If a file spanned more than 2 lines on the display then the top line (the end of the file) would always be drawn all the way to the right side of the display

MyDefrag v4.1.1

Changes:

Optimized the subroutine that searches for contiguous fragments.
Fixed a bug that would prevent the program from running (immediate finish) without a proper error message, if there was a directory called "Settings" anywhere in the path. Also added some extra error messages in case there is a problem executing a script.
Optimized the subroutine that vacates items out of the way.
Disabled the OtherInstances(ask) setting for the screensaver.
The "F1" key now looks for the manual in the installpath, instead of always using "C:\Program Files\MyDefrag v4.X\Manual.chm".

MyDefrag v4.1.2 (August 2, 2009)

Changes:

• Deleted the LowMemoryUsage() setting. The program no longer caches the full paths of regular files. but still caches directories.
• Added a new defragmentation algorithm, the old algorithm is now available as Defragment(Fast).
• The list of fragmented files in the logfile will now show the count of wrap-around fragments, instead of the count of fragments.
• Fixed a bug that would cause the "MyDefrag.debuglog" file to be created even if the "-d 0" commandline parameters was specified.
• Added the SortByNewestDate() fileaction.
• Fixed a bug that prevented MyDefrag from processing files that were encrypted by another userid than the userid that was running MyDefrag.
• Fixed a bug in the AddGap() fileaction. It created gaps that were too big.
• Added the IgnoreWrapAroundFragmentation setting.
• Gaps are now also skipped by the wrap-around fragmentation analyzer.
• Added the FastFill(WithShuffling) option.
• Added some code to protect against circular folders.
• Made some changes in how the screensaver will stop in various circumstances.
• Changed the way that the !RunTime! macro is calculated.
• Fixed a bug that could cause an infinite loop on very full harddisks when trying to move files out of the way (vacate).
• Enlarged the width of short numbers from 7 to 11 characters.

MyDefrag 4.2.1

Changes:

• Fixed a bug where a StatusBar() command in a script would turn off the statusbar in the screensaver, irrespective of the choice made in the screensaver settings dialog.
• Added the script- and disk-selection menu.
• The program now remembers the size and position of the window on the screen.
• The Settings.MyD script is now always executed by the program itself, and needs no longer be called from within a script.
• Moved the translations to the Settings.MyD script, and removed the Language.MyD script.
• Hardened the screensaver against improper installations, for example when the executables have been copied to another machine (without using the MyDefrag installer).
• Fixed a bug where the program could get confused when filling a zone and start filling from the beginning of the disk, when it encountered an NTFS compressed file.
• Changed the SelectNtfsSystemFiles() so it also selects all files in all subfolders the $Extend folder. Previously it only selected files in the base $Extend folder, and only filenames than began with "$".
• Strengthened the behavior if the Microsoft defragmentation API refuses to move a file into a gap. For example the sorted placements will now skip the gap after more than 10 failures.
• The WhenFinished(shutdown) and WhenFinished(reboot) settings are no longer executed when a script is cancelled.
• Fixed a problem in the scrolling and zooming calculations.

MyDefrag 4.22
Oct 11, 2009

Changes:

• Moved several more strings to the Settings.MyD file so they can now be translated.
• Fixed a bug that would prevent scripts from showing up in the script chooser if the script contained a macro, for example the !Include PATH! macro.
• Fixed a bug that would crash the script chooser if the user clicked an empty line in the box of scripts.
• The installer no longer offers to create a scheduled task on Windows 2000. It uses the Windows "Schtasks.exe" commandline utility for that, but that utility does not exist on Windows 2000.
• Fixed a bug in the AnalyzeOnly script where the statistics per disk were not appended, but would overwrite the entire previous statistics.
• Changed the way the window positions are saved & restored so they cannot not end up off-screen if the screen has been resized.
• Renamed WindowSize(normal) into WindowSize(restore), and added WindowSize(fixed).
• Fixed a bug where the program could enter an infite loop if paused while showing the statistics. This also solves the problem of the statistics not being filled with the numbers.
• Fixed a bug in the FastFill action where the program could go into an endless loop if a gap was followed by an unmovable file and all items above the gap were bigger than the gap.
• Fixed a bug in a subroutine that is used by FastFill and SortBy, which was causing various erratic behaviours such as unfilled gaps and files not moved to the proper zone.
• Fixed a bug that was causing the program to use excessive amounts of memory and in some cases to crash with a "Memory full" error.

MyDefrag v4.2.3
October 12, 2009

Changes:

• Changed the * FullPath fileboolean. It now has separate parameters for the directories and for the filenames, and is considerably faster.
• Added the * DirectoryPath fileboolean.
• Renamed the !TotalDiskSpaceBytes! macro into !DiskSpaceTotalBytes!, and !TotalDiskSpaceGigaBytes! into !DiskSpaceTotalGigaBytes!. Added new macros !DiskSpaceFreeBytes!, !DiskSpaceFreeGigaBytes!, !DiskSpaceUsedBytes!, and !DiskSpaceUsedGigaBytes!.
• Fixed a bug in the script chooser that caused it to display a different description than for the selected script.

MyDefrag v4.2.4
October 27, 2009

• Fixed a bug in the Title() setting that caused it not to replace macros.
• Fixed a bug where a change in the size of the windows would not be remembered if the windows were not moved away from the top-left of the screen.
• Added a parameter to * PlaceNtfsSystemFiles to set the size of the NTFS reserved area.
• Added the !ProgressPercentage! macro.
• The script chooser will no longer display volumes that are excluded with ExcludeVolumes() in the Settings.MyD file.
• Changed the syntax of the * MakeGap and * AddGap actions. It is now possible to place zones anywhere, they do not have to be placed one-after-another from the beginning of the disk.
• Changed the default scripts so that the MFT, some other NTFS system files, and the directories, are now placed 30% into the data on the disk.
• Fixed a bug in the screensaver that would not display the progress percentage.
• Fixed a bug in the graphics code that will properly show StatusBar(path) if StatusBar(Status) is not specified.
• Changed the vacate function so that when there are no gaps above the end of the zone, it will use the highest gap available. Before it would use the first gap available.
• Changed the default script for the screensaver into Optimize Daily. Before it was Optimize Weekly.
• Changed the default setting for the status bar of the screensaver into Full Status Bar. Before it was No Status Bar.
• The positions of the windows are now also saved when the windows are moved and not only when they are resized.
• If the Windows defragmentation API has not succesfully moved an NTFS compressed file then MyDefrag will no longer try to move the file with the alternative method, but leave the file where it is and mark it as unmovable. The alternative method is extremely slow for compressed files.
• Made a change that should increase the chance of succesfully moving files on Windows 2000 machines. Sometimes files could not be succesfully moved and they would be marked as unmovable.
• Fixed a bug that caused unnecessary work and unfilled gaps at the end of a zone for the SortBy fileactions.
• The script chooser window will now list scripts that contain a syntax error. The description of the script shows the error.
• Fixed a bug where the subroutine that determines if a file is fragmented (see the IgnoreWrapAroundFragmentation setting) would treat gaps as unmovable.
• Fixed a bug that caused the program to skip very big FAT volumes.
• If the Sortby fileactions find two files to be equal (for example SortBySize and files with equal size) then the program will now also compare the Inodes. This reduces the number of filemovements.
• The !Include PATH! macro is now evaluated before any other macros, so that macros inside the included file will be processed.

MyDefrag 4.2.5

Changes:

Added the !InstallDirectory! macro.
Added the !ScriptDirectory! macro.
Added the !ExecutableDirectory! macro.
It is now possible to use macros inside included files.
Added the ProcessPriority setting.
The MakeGap() and AddGap() functions before v4.2.4 would automatically scale down a gap if it would not leave enough room for the remaining data to be processed. This limiting is now removed.
Added an extra test to make sure the script chooser will only list "*.MyD" files, and not for example "*.MyD~".
Fixed an infinite loop for unmovable NTFS compressed files.
Fixed a bug that prevented the PreventScreenSaving() and PreventPowerSaving() settings from working if they were placed in the Settings.MyD file.
Fixed an infinite loop problem for extremely rare cases where the Microsoft defragmentation api returns an empty list of extends.
Change the tree locking timeout from 15 minutes to 2 minutes.

MyDefrag v4.2.6

Changes:

Changed the script chooser so that now all disks are deselected by default.
Fixed a problem in the calculation of the beginning and end of a zone. The gap that PlaceNtfsSystemFiles() makes for the NTFS reserved area was sometimes counted twice, causing the next zone to start too far up.
Changed the syntax so that number multipliers (such as MB and Gi) can now be used with floating-point numbers, not only integer numbers.
Added the RoundDown() function for calculating numbers.
Added extra debugging code in an attempt to find the reason why the screensaver sometimes crashes.
Changed the default debug level to zero.
Fixed a bug in MakeGap() and AddGap() that sometimes caused the program to crash.
Fixed a bug in the calculation of the ZoneSize number.
