This is the software publisher's description.

Disk Suite is an all-in-one hard-drive management utility that integrates disk optimization and cleanup, defrag, partitioning and backup in one easy to use package. Disk Suite puts a range of tools at your fingertips to provide optimum system performance and improved stability and security.

With Disk Suite you can safely cleanup and optimize your Windows disks with a few simple mouse clicks. Disks can become bloated with temporary files, log files and other unnecessary data. The cleanup and optimize feature lets you safely remove unnecessary files and bloat from your PC without detailed knowledge of the Windows file system.

It's a fact that fragmented drives drain critical system resources, compromise the ability to access your files efficiently and slow down Windows start-up. The defrag feature provides you with a powerful defragmentation tool that supports both NTFS and FAT file systems. Different levels of defragmentation are provided in case you just need a quick defrag or you want to schedule a complete optimization of your disk.

The Backup feature allows you to make copies of your data that can be restored in the event that files become lost, damaged or corrupted. Taking regular backup is one of the most important steps you can take to ensure you don’t lose irreplaceable data and files such as photos, documents and other information.

The Partition feature allows you to create, merge, split, resize, delete, copy, and move partitions without losing data. It also lets you manage your partition structure by allowing you to change cluster sizes, convert to different file systems and much more.

The repair feature performs integrity checks to check file system structure, surface scans to check for bad sectors and disk errors as well as repair hard drive problems. In addition the repair feature includes hard disk diagnostics and lets you review the information including the S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) status of your hard drive (if supported).

Note that this is the final official release of PC Tools Disk Suite.
