JkDefragGUI is an Graphical User Interface which allows you to easily select all the features JkDefrag, a freeware defragmentation tool made by Jeroen Kessels has to offer. But is can do a lot more. JkDefragGUI can schedule a defragmentation, install JkDefrag or it's screensaver but can also do some small maintenance to your computer. It can be used to schedule a defragmentation of your system files like pagefile and registry files. JkDefragGUI also supports CCleaner which can be used instead of the internal cleaning function. It can also erase any information which is left behind on your hard disk after erasing files. JkDefragGUI was created for people who don't have the skills of an advanced user but still want to use the powerful features JkDefrag has to offer or for those people who like a GUI instead of using the command line.
JkDefragGUI is compatible with Windows 2000, Windows XP, Windows Vista, Windows 2008, U3 capable flash memory and with BartPE pre-installed environment.
Defragmentation and optimizing will not only make a harddisk faster, but also lengthen it's life span. The disk will have less work to do and therefore have less wear and tear. Secondly, the sorting optimization strategies (see the "-a" option) will refresh all the magnetic data on your harddisk. However, defragmenting and optimizing is work, so excessive defragmenting and optimizing can actually cause more wear and tear than it prevents. JkDefrag is therefore set for "fast" optimization by default, intended to be used on a daily basis. The other optimizations should only be used occasionally.
Phase 1: Analyze JkDefrag has to scan all the files on the disk to determine if they are fragmented and where they are. A second step inside this phase will apply the exclude masks and determine which files are SpaceHogs.
Phase 2: Defragment All fragmented files are defragmented, simply by moving them to the first gap on the disk that is big enough. If there is no gap big enough then the defragmenter will reduce the number of fragments in the file by moving as much of the file as possible into the largest gaps available.
Phase 3: Optimize On most harddisks the beginning of the harddisk is considerably faster than the end, sometimes by as much as 200 percent! See the link to "HD Tune" in the "See Also" chapter for a nice little free program to measure your disk. The default JkDefrag optimization strategy therefore moves all files to the beginning of the volume. It is intended for daily use and will simply fill gaps with files from above, very quick and with very little data movement.
