RatDVD takes a full featured DVD-9 movie and puts it into a highly compressed .RatDVD container format file of about 1.x GB in size while preserving all the features of the original DVD. You can directly play back the .RatDVD file in Windows Media Player or any other compatible player with all the options the original DVD movie would give you. You can also convert it back to the original DVD format, burn it and watch it on any DVD player.

Of course this program uses some kind of compression to achieve such a small file size. It is in fact a codec written by the author of the program itself, named XEB. Why did he write his own codec? First to create the option to store many of the original features of the dvd. Second to avoid the patents of codecs like XviD, H264 and others to keep the program free.

This is, as the name suggests, a disk defragment and optimize utility. It can not only handle hard discs but also usb disks, usb sticks and floppies.

The program is available in several versions and is completely automatic by default, although you can control the behavior of every version through the command line. The windows GUI version is really bare bones, there are no buttons or pull down menus. It only shows its current action and progress in a high detail map of your hard disc. The command line version is for use in an automatic environment like the task scheduler, administrator scripts and so on. The final version is a screensaver version whose use should be obvious.

JkDefrag is based on the standard defragmentation API by Microsoft, a standard system library in Windows. Most defraggers, including commercial ones, are based on this API. JkDefrag is therefore very solid and there is no risk of losing data. You can stop the program at any time with alt-f4, the close button of the window, the pulldown menu of the taskbar, the task manager or another utility and it will finish the current file in the background.

Hold it. For everybody who would like more control through a GUI and not through the command line there is a separate frontend available which also doubles as a frontend for the former Sysinternals (now Microsoft) utility PageDefrag. This small utility will defragment your system files at reboot.
