Jwansoft Disk Defrag is a small and free tool to defragment your hard drive. With this software, we can optimize and speed up your operating system by organizing the contents of individual partitions. The application has a simple and clear user interface, and is characterized by a modern algorithm, which makes the defragmentation process much faster and safer.

In addition, it is fully compatible with almost all file systems (NTFS, FAT16, FAT32). After starting the program you get a clear list showing all partitions with their parameters - status, volume name and size on the hard disk. In addition to the most important function for partition defragmentation, it also includes a tool for conducting a thorough analysis of the disk structure, displaying the arrangement of individual clusters on the hard drive.

This will allow us to find out which locations on the partition require defragmentation and optimisation. Jwansoft Disk Defrag has three different operating modes. The first one only defragments all locations on the data carrier.

The second and third perform the same as the first mode, but also optimize the drive, which results in solving problems with slow and unstable operation of the entire operating system. For more experienced users, there is also a special function to organize the structure of the hidden MFT (Master File Table) file, which contains all the most important information about the files.
