Auslogics Disk Defrag is designed specifically for fast optimizing today's modern hard disks.
Disk fragmentation leads to system slowdowns, PC crashes, slow startup and shutdowns, and sometimes to system failures.
Hard disks are by far the slowest component of your computer. Therefore fragmented disks often become a bottleneck of the system performance. Besides causing slowdowns, fragmentation makes the hard drive disk heads frequently move when reading files, leading to freeze-ups and system crashes. It is important to keep your disks defragmented and optimized as much as possible.
Limitations:
The free version includes nag-screens and offers other Auslogics apps during install as well as in-app. For $99.95 you can upgrade to the pro version which additionally includes Special Algorithms for SSD, Disk Cleanup before Defrag, Wipe Free Space on Drives, and Schedule Automatic Defrags.
Use Defraggler to defrag your entire hard drive, or individual files - unique in the industry. This compact and Windows application will fully support NTFS and FAT32 file systems. Portable version available.
