Frequently Asked Questions: Auslogics Disk Defrag

Question:

Why are some of the files skipped by the program?

Answer:

Disk Defrag sometimes skips certain files because they are locked by another running program. Common solution would be to exit all running applications when you defragment your disk. Some files (MFT, etc.) are skipped because they are system files and cannot possibly be defragmented with this program.

Disk Defrag also needs a contiguous disk space for each file to be defragmented. If your disk has a lot of free space, but it is broken into small free space intervals, Disk Defrag is unable to defragment some of the large files (such as movies, etc.). To tackle this problem, you can run “Defrag & Optimize” mode. It will consolidate the free space into a contiguous block and defragment even largest files on your disks.

Disk Defrag can defragment hard drives with as little as 1% of free space available. However, better results can be achieved if there is at least 10% of free space on the disk.
