MyDefrag 4.2.1

MyDefrag (formerly JKDefrag) is a disk defragmenter and optimizer for Windows 2000/2003/XP/Vista/2008/X64. 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.

Included are a Windows version, a commandline version (for scheduling by the task scheduler or for use from administrator scripts), a screensaver version, a DLL library (for use from programming languages), versions for Windows X64, and the complete sources.

Why use this defragger instead of the standard Windows defragger?

• Much faster.
• Totally automatic, extremely easy to use.
• Optimized for daily use.
• Disk optimization, several strategies.
• Directories are moved to the beginning of the disk.
• Reclaims MFT reserved space after disk-full.
• Maintains free spaces for temporary files.
• Can defragment very full harddisks.
• Can defragment very large files.
• Can defragment individual directories and files.
• Can be run automatically with the Windows Scheduler.
• Can be used from the commandline.
• Can be used as a screen saver.
• Can be run from cdrom or memory stick.
• Sources available, can be customized.

* 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.
