Analysing a drive’s state of health with S.M.A.R.T.

In O&O Defrag 25 the S.M.A.R.T. functionality has been integrated for the very first time. This indicates the “health status” of hard disks, SSDs and RAIDs whenever there is any problem. Such a problem could be a high temperature or an error reported by the drive itself. If there is anything unusual going on, a message will be displayed in the Windows Action Center.

O&O Defrag supports Windows Compact OS

Many new things have been added to the O&O Defrag engine that make using it, especially under Windows 10, even better. That‘s why version 25 now supports the Windows 10-integrated feature for compressing system files so that more space can be kept free.

“Install & That’s All”: After installation, no further settings need to be configured. The program selects and implements the defragmentation method best suited to the system.
