O&O Defrag Professional is a powerful software made to defragment your computer and to improve its performance in this way.
O&O Defrag merges the individual fragments from files and then sorts all data into separate zones.
Disk defragmentation has several methods to be run - Stealth (the fastest), Space (consolidates data, and further fragmentation is prevented), Complete / Name, Complete / Modified, or Complete / Access (these three methods also reorganize file structure in alphabetical order, or according to the last time when they were modified or accessed).
You can schedule defragmentation every time you want, or when the computer is idle and you can also manually select individual files or folders to be defragmented.
O&O Defrag makes it possible to optimize SSD drives through TRIM commands and can analyse your disk to find possible errors.
You get reports for your drives, both while defragmenting and also after process ending, with plenty of details regarding clusters, paging files, locked files, etc.
