JkDefrag v3. The program is now called “MyDefrag”, because it has a scripting language and you can customize just about every aspect of it.
It is no longer the “JK” defragger, but “my” your defragger! Fully functional freeware. With scripting language. Improved interface. Higher speed. Better optimization. Lower memory usage. Extensive documentation. Easier to install. 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. JkDefrag is completely free, no cost, no time limit. If you’ve payed for your copy then you’ve been scammed! Release date: August 31, JkDefrag There is no “setup” or “install” and no configuration file. All you have to do is download the zip and unpack anywhere you like.
The programs are ready to run, even from memory stick or cdrom. The zip contains the following 3 programs: JkDefrag. This is what most people will use. No installation or configuration necessary, it’s ready to run and will automatically process all the mounted, writable, fixed volumes on your computer JkDefragCmd.
Specially designed to be run automatically in the background, or from administrator scripts. See the “Commandline” chapter below for a list of commandline options, and the “Frequently Asked Questions” on how to run it automatically with the Windows Scheduler. Note: screen savers do not lengthen the life span of CRT and LCD monitors, contrary to popular belief they only prevent burn-in. It is better to let the monitor be turned off by the Windows energy saving settings. On a default Windows system the “administrator” userid has full permissions to all files and disks.
Note: On Vista right-click the JkDefrag program and select “run as administrator”. Stopping All versions of JkDefrag can be stopped safely at any time, there is no risk of losing data or corrupting your disk. You can use all the usual ways to stop a Windows program, such as pressing ALT-F4, clicking the ‘x’ in the top-right corner, via the pull-down menu in the taskbar, or by killing the program via the task manager or another utility.
It may take a bit of time for the program to actually stop, JkDefrag will finish the current file in the background. 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. Sorting the files on your disk can give you even more speed. There are several sorting strategies to choose from see the “-a” options. These are all very slow and intended for occasional use only. Windows reserves a percentage of the disk for the MFT Master File Table , but can place normal files there if the rest of the disk is full. The files will remain there, even when there is enough space again. JkDefrag looks for files in the MFT reserved space and moves them to normal diskspace, making the reserved space available again for the MFT.
When JkDefrag is running you will see lot’s of messages zipping by showing you exactly what is happening. The messages are also stored in the logfile “JkDefrag. The logfile may also contain warning messages, for example when a file could not be moved.
This is normal, no need to worry. Windows has many system files that cannot be moved while Windows is running. JkDefrag is completely automatic. The commandline options are not needed for normal use. JkDefrag is ready to run, just click the “JkDefrag” program.
Default behavior is to automatically process all the mounted, writable, fixed volumes on your computer. You can change this behavior with the following commandline options: For example:. The action to perform. The items will not be defragmented and will not be moved.
If the mask contains a space then it must be enclosed in double-quotes. Files that match a mask will be moved to the SpaceHogs area. The program has a built-in list for all files bigger than 50 megabytes, files not accessed in the last month, archives, files in the recycle bin, service pack files, and some others.
Disable this list by specifying the special mask “DisableDefaults”. Slow down to N percent Default is
