Frequently Asked Questions: Auslogics Disk Defrag

Question:

What is "Free space not found" error?

Answer:

Disk Defrag 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.
