Defraggler options - Defrag tab
Note: For details about the Do not move 'Large Files' during Defrag Freespace option, see this topic.
Hard drives are fastest at the beginning of the drive, and slowest at the end of the drive. That means that you'll get the best performance from your PC if your most-used files are placed at the beginning of the drive.
Defraggler enables you to move large files to the end of the drive. Typically these large files are video or storage files, so they're not used very often. By moving them to the end of the drive, you're freeing up 'fast space' for files you use far more often. You can control which types of files and what sizes of files Defraggler moves.
In this example, we'll add VMDK files as file types we'd like Defraggler to move to the end of the drive. VMDK stands for VMWare Virtual Machine Drive files. This is only an example - if you use VMDK files, you would have to make the determination as to how frequently they are used.
To add a VMDK file type for Defraggler to move:
You can modify and delete existing Category entries using the Edit and Remove buttons. Click OK once you have finished making changes on this tab.
Note: If you select Move large files to end of drive but do not specify file types, Defraggler will attempt to move all files equal to or larger than the size in the Minimum file size text box.
