O&O Defrag Professional 25 Overview

Product Name: O&O Defrag Professional 25
Official Website Link
Supported Systems: Windows 11, 10, 8

O&O Defrag Professional 25 helps to maintain the optimal system performance of your Windows PC by defragmenting the HDDs or SSDs. The program comes with a simple easy interface and offers fully automatic defragmentation settings.

With the usage of the PC over time, fragmentation of the hard disk happens and it takes more time to access your file system during your daily routines. This is why you need to scan the Windows system and hard drives occasionally for such issues and defrag them if necessary.

This defragmentation program reorganized fragmented files on the hard drives, sorted and combined them securely together. The defragmentation process runs in the background without interrupting or affecting the current work.

O&O Defrag Professional comes with more additional functions. The Disk Cleanup module enables you to analyze and clean temporary files, downloaded Windows updates and error reports, thumbnail cache, etc. You can also select a drive and check them for errors using Check Drive(s) function.
