Defraggler uses internally-stored settings to determine how it appears and operates. You can modify these settings by setting Defraggler to create an external INI file and editing it. INI files are in plain text, so you can edit them with Notepad or manipulate them with other programs.
The Defraggler INI file must be located in the application installation folder (typically, C:\Program Files\Defraggler). By default, the INI file does not exist when you first install the application. To have Defraggler generate it automatically, set the option for Defraggler to save its settings to an INI file.
To modify Defraggler's behavior using an INI file:
- Create or open the INI file in Notepad.
- Use the following entries as a reference.
| Entry | Description | Notes |
|---|---|---|
| [Software\Piriform\Defraggler] | INI file header. | Do not modify. |
| MainWindowTopSplitterProportionalPos | Vertical proportion of Drive section of Defraggler to the entire program window. | Determines how tall the Drive section is compared to the entire Defraggler window. This number plus the next number must add up to 5693. Example: setting this number to 500 means that the Drive section would be 500/5693 * 100 = 8.8% of the vertical height of the program window. The next number would have to be set to (5693 - 500) = 5193. |
| MainWindowBottomSplitterProportionalPos | Vertical proportion of Drive Map section of Defraggler to the entire program window. | Determines how tall the Drive Map section is compared to the entire Defraggler window. This number plus the previous number must add up to 5693. |

| LargeFilesCategories | Lists the categories of large files for Defraggler to move, all on one line. To add a new category, use the following syntax: <Name>;[selection flag]| Example 1: Test;1| This would create a new category called Test that would have a check box by default. Example 1: New;2| This would create a new category called New that would not be selected by default. If you create a new category, you must add extensions to it in the next entry. |
|
| LargeFilesExtensions | Lists the file extensions for the large file categories for Defraggler, all on one line. To add a new set of file extensions, use the following syntax: <*.[ext1]|*.[ext2]|etc. Example: <*.tst|*.ts2 This would include files with the extensions .TST and .TS2. Note: The order of the set of file extensions corresponds to the order of the categories in the entry above. For example, if your new category is fifth in the category list, its extensions must be fifth in the extension list. Note #2: Do not precede the first set of extensions with a left-angled bracket ( < ). |
