JkDefrag Portable

Portable JkDefrag is a lightweight piece of software designed to help you reduce fragments on the disks to improve stability and file access speed. It is designed as a portable version for JkDefrag.

Since there is no installation pack involved, you can extract the program files to any part of the hard disk and just click the executable to run. There is also the possibility to save Portable JkDefrag to a USB flash disk or similar storage unit, in order to run it on any PC with minimum effort and no previous installers.

An important aspect worth taking into account is that the Windows registry and Start menu do not get updated with new entries, and no extra files are created on he disk, thus leaving no traces behind after its removal.

The GUI is represented by a small and classical frame that loads a list with all available disk drives at startup, together with information such as file system, fragmentation in percentage capacity, and free space.

You can get started by selecting a partition to perform an analysis and find out whether it is necessary to defragment it or no. There are two types of defrag jobs available: fast and thorough. The later one also optimizes files, so it clearly takes a longer while to finish. All activity is recorded to log files that you can examine at a later time.

We have not come across any issues in our tests since Portable JkDefrag did not hang, crash or pop up error messages. It has a good response time and uses low CPU and RAM. Although it is not feature-rich, Portable JkDefrag gets the job done and can be used by anyone with ease for defragmenting hard disk drives.
