Logfile JkDefrag writes all messages to a logfile called "JkDefrag. You can inspect the logfile if you want, it's a flat-text file. The logfile is automatically cleared when the program starts, it does not grow to infinity. The Windows version of JkDefrag shows a high-detail map of the harddisk, refreshed 3 times per second.
Bottom-left of the window is the beginning of the harddisk. The program is completely automatic, there are no buttons and no pull-down menu's. Tip : Reboot before running JkDefrag. This will release files that are in use, so they can be defragmented.
You can also run JkDefrag in Windows safe mode press F8 while booting to defrag even more files. Tip : Stop your real time virus scanner before running JkDefrag. Virus scanners check all disk activity, making defragmentation and optimization very slow.
Tip : Move the swap file to another volume, reboot, defragment, and move the swap file back. If you don't have a second volume then temporarily make the swap file small, for example Mb. Tip : If an application for example a database prevents certain files from being defragmented then stop the application, run JkDefrag for the particular data directory only, and restart the application.
Tip: Package unused files with a packager such as 7-zip. The packagefile not only takes less harddisk space, but will also defragment and optimize much faster than the individual files. Note : This does not apply to Windows NTFS compression, which will actually make defragmentation and optimization a lot slower. Tip: Buy the biggest harddisk you can afford. Investing in a bigger harddisk gives more speed-per-dollar than investing in a faster CPU or more memory.
Tip: The first partition on a harddisk is significantly faster than other partitions. Tip: If you have 2 physical harddisks of the same speed , then place the pagefile on the first partition of the second harddisk. Most defragmenters are based on this API, including the free defragmenter that comes with Windows and many commercial defragmenters.
JkDefrag does not modify the disk by itself, and is therefore extremely solid. 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 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. JkDefrag classifies files into 3 zones: directories zone 1 , regular files zone 2 , and SpaceHogs zone 3. Directories are perhaps the most accessed data on disk, so zone 1 is placed at the beginning of the harddisk.
After the directories comes a free area see below , then zone 2 with regular files, another free area, and then zone 3 with SpaceHogs less important files that take up a lot of space. The beginning and end of the zones is determined automatically, see the "-f" option. A running computer will create and delete temporary files like there is no tomorrow.
If the harddisk were completely optimized then the only place for new temporary files would be behind all the other data. Which is rather slow.
