    Program overview

      Defragmentation is the process of optimizing the logical structure of the disc by storing the files in a continuous sequence of clusters. Defraggler is able to defragment a whole drive and individual files and folders in the normal or fast mode. Defragmentation can normally take more than 2 hours, and fast for a few minutes. To obtain maximum benefit from defragmentation, program must use the normal mode.

    • RAM: 128 MB or above.

    Features of the program

    • Evaluation of disk performance. During the evaluation, the program will display the number of fragmented files, fragments and disk read speed (MB / sec).
    • Search for files by name and size, including non-fragmented files.

    • Analysis of the logical structure of the disc and the collection of the necessary information about the fragmented files, excluding the files from System Restore points and the hibernation file.
