MyDefrag 4.2.6

MyDefragMyDefrag (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.

JKDefrag was open source, but from version 4, when it changed its name to MyDefrag, it is closed source.

Change Log:

- 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.
