To change the language Defraggler uses, select the language from the Language drop-down box.
Defraggler can be run in 43 languages: Albanian, Arabic, Armenian, Belarusian, Bosnian, Bulgarian, Català (Catalan), Ceský (Czech), Chinese (Simplified), Chinese (Traditional), Croatian, Danish, Deutsch (German), English, Español (Spanish), Estonian, Français (French), Georgian, German (Deutsch), Greek, Hebrew, Indonesian, Italiano (Italian), Japanese, Kurdish, Latvian, Lietuviu (Lithuanian), Macedonian, Magyar (Hungarian), Nederlands (Dutch), Norwegian, Persian, Polski (Polish), Portuguese (Portugues), Português do Brasil (Brazilian Portuguese), Romana (Romanian), Russian, Slovak, Slovenian, Suomi (Finnish), Svenska (Swedish), Türkçe (Turkish), Ukrainian, and Vietnamese.
The temperature displayed for the drive in the Health tab may also be changed from Metric (C) to Imperial ( F) or visa versa here - we recommend using Metric, however, as most datasheets, product manuals, and the like will display the drive's tolerances in this manner.
To automatically check for updates online, select Automatically check for updates to Defraggler. You must have an active Internet connection for this option to work. In paid versions of Defraggler, you also have the option to Enable silent background updates, allowing the software to autonomously update without notifying you, making the process entirely automatic.
You can also change which drives are displayed by Defraggler with the following settings:
- Show SSD drives: Unchecking this box will keep Defraggler from showing SSDs; since SSDs should not be defragmented, this helps prevent this from being done by accident, though it does then prevent you from using the Optimize procedure instead.
- Show removable drives: Unchecking this box will keep Defraggler from showing removeable drives such as USB Flash drives. Typically, these drives would not need to be defragmented, and defragmenting them may even be harmful to them, similar to SSDs.
- Show unmounted drives: Unchecking this box will keep Defraggler from showing drives that are physically connected to the computer but whose file systems are not connected to Windows. This is unchecked by default as Defraggler would not be able to work on such drives.
- Show ejected drives: Unchecking this box will keep Defraggler from displaying removable drives that have been ejected from the system, much the same way that Windows File Explorer does.
