Defraggler is an application for defragmentation of a hard disk drive. With Defraggler, you can defragment the entire drive as well as individual files and folders on it. The program supports NTFS and FAT32 file systems, allows you to exclude files by name, extension and other parameters from defragmentation, and can transfer the heaviest files away from the beginning of the disk, which allows the computer to work faster.
Before you begin defragmentation, you can browse the interactive map of the hard disk fragmentation and decide whether to defragment it. If you have little time to complete defragmentation, the program allows you to use the fast defragmentation mode. Installation of programs, creation and deletion of files cause the free disk space to be distributed over the surface of the disk by uneven partitions, which may result in slower system operation. Defraggler eliminates this problem and defragments the free space on the hard disk. This application has a built-in scheduler that allows you to defragment the disk at any time convenient for you (for example, when you are not busy working on your computer). The program has a small size, and its portal version can work from external media.
