MyDefrag v4.1.1

MyDefrag (formerly JkDefrag) is a disk defragmenter and optimizer (a maintenance utility to make your harddisk faster) for Windows 2000, 2003, XP, Vista, 2008, and for X64. It is freeware, no time limit, fully functional, no advertisements. Fast, low overhead, with many optimization strategies, can handle floppies, USB disks, memory sticks, and anything else that looks like a disk to Windows. Included are a set of easy to use scripts for endusers, a scripting engine for demanding users, a screensaver, and a combined Windows plus commandline version that can be scheduled by the Windows task scheduler or for use from administrator scripts.

What's new:

  • Optimized the subroutine that searches for contiguous fragments.
  • Fixed a bug that would prevent the program from running (immediate finish) without a proper error message, if there was a directory called "Settings" anywhere in the path. Also added some extra error messages in case there is a problem executing a script.
  • Optimized the subroutine that vacates items out of the way.
  • Disabled the OtherInstances(ask) setting for the screensaver.
  • The "F1" key now looks for the manual in the installpath, instead of always using "C:\Program Files\MyDefrag v4.X\Manual.chm".

Wikipedia - USB (File system)

Flash drives can be defragmented, but this brings little advantage as there is no mechanical head slowed down by having to move from fragment to fragment (flash drives often have very large internal sector size, especially when erasing so defragmenting means accessing fewer sectors to erase a file). Defragmenting shortens the life of the drive by making many unnecessary writes.

Just be careful about that one. An external USB hard-drive doesn't have this limitation.

i agree... defraging USB drives is overall 'not worth it'.

because in theory he claims defraging USB Thumb Drives helps which he talks about in the quote here which i got right from the website...

Many people think that flash memory does not benefit from defragmentation and optimization because bandwidth and access time are the same for the entire flash memory, unlike harddisks which are faster at the beginning than the end. But fragmented files need extra processing time inside Windows, not noticeable on slow harddisks but very significant on fast flash memory disks. Even more important is free space optimization. Flash memory is written in large blocks, and if free space is fragmented then Windows has to (read and) write much more data than the size of the file. This takes time, which translates into lower speed.

This looks very similar to JK Defrag even the logo is similar...

a good Defragmenting program although they should make it slightly easier to use as far as selecting individual drives as it's all script/editing the shortcut's commands etc to get it to do that sorta stuff.
