Support
For help getting JkDefrag Portable up and running, please read the following:
Defragmenting Flash Drives: Flash media has specifically been excluded from the drive list as flash drives should not be defragmented (it does not increase access speed and shortens the life of the drive). If you wish to enable it anyway, copy the .ini file from Other\Source to the root JkDefragPortable directory and set EnableFlashDrives=true.
