The windows application is a simple application with one main form of fixed size and an about box. An illustration of the window as well as an explanation of their functionality is below:

1. List of volumes This list all drives on the machine that you can scan. CDROM's and other drives that cannot be defragmented are excluded from list automatically. If the Skip removable media box is checked, also floppies and other similar devices will be excluded. This list has the following fields:

   • Volume - drive letter plus file system type in square brackets. There are used two types of icons in this field: for fixed drives and for removable media.

   • Status - a description of the action being performed.

   • Total space

   • Free space

   • Percentage - percent free.

2. Skip Removeable Media Checkbox

3. Cluster Map This is a color coded representation of all drives. Here is colors explaination:

   

   Some of the categories on the legend have a lighter and darker color on them. The lighter colors represent files below the file size threshold, and the darker colors represent files above the threshold if one is set. The cyan color represents space temporarily allocated by system.

4. Rescan Drives (Ctrl+R) This button will recheck all volumes in the system to see if some were added or removed.

5. Buttons The following section explains the buttons along with listing their shortcut keys.

   • Analyze (Ctrl+A) Scans the currently selected drive to determine how fragmented it is.

   • Defrag (Ctrl+D) Exactly what it says.

   • Settings (Ctrl+T) This button starts the UltraDefrag GUI Configurator program.

   • Compact (Ctrl+C) Moves all files to the beginning of the partition, defragmenting them if possible. The compact command does not work on volumes with the FAT filesystem because you cannot move directories on them.

   • Stop (Ctrl+S) Stops the currently running analyze or defrag operation.

   • Fragmented (Ctrl+F) Display a report of all fragmented files on the volume. This report is very small but useful. It is generated by the driver, so all versions of UltraDefrag generate it.

   • About (F1) Displays the simple about box containing copyright notice and links to most important information about program.

6. Shut down PC after a job Check this box if you wish to automatically shut down the PC after a job. Note that your system and hardware configurations must support shutdown and power off, otherwise Windows may reboot your PC or even do quite nothing. So, test this mode before using it at regular basis.

   Instead of the system shutdown you may specify the hibernation. Click Settings button to open the Configurator. Click Options button inside a Graphical interface section and set hibernate_instead_of_shutdown = 1 as described below. Note that your system must support hibernation and it must be turned on. Otherwise Windows will display a message box containing brief error description and system will not be switched to hibernation mode.

7. Progress bar This displays the progress of the currently running analyze, compact or defrag task. Note that selecting a different volume will cause this bar to disappear.

To configure UltraDefrag push Settings button on the main GUI window. This action opens the UltraDefrag GUI Configurator:

Configurator's window contains three sections:

1. Graphical interface Buttons in this section provides an access to GUI related options.

   • Font Opens the font selection dialog. Choose your preferred font for GUI application rendering. The default font is Courier New, 9

   • Options Opens the guiopts.lua file for editing. To understand meaning of GUI options read please carefully the console application section of this document. GUI options have the same meaning as environment variables accepted by console interface.

     Note that you must specify paths in filters with double back slashes instead of the single. Par example:

     ex_filter = "MyDocs\\Music\\mp3\\Red_Hot_Chili_Peppers"

     Here is the complete example of the script:

     -- UltraDefrag GUI options
     
     in_filter = "windows"
     ex_filter = "temp;tmp"
     sizelimit = "25M"
     refresh_interval = 100
     disable_reports = 0
     dbgprint_level = "PARANOID"
     
     -- set this parameter to 1 if you prefer to hibernate system
     -- after a job instead of shutting them down, otherwise set it to 0
     
     hibernate_instead_of_shutdown = 1
     
     

   • Help button opens this section of the Handbook. If you have a local copy of documentation installed, the Configurator will use it. Otherwise the same page will be loaded from the project's web site.

2. Windows boot time scan This section contains options of the boot time defragmenter.

   • Enable checkbox gives you an ability to turn on/off the boot time defragmenter by one click.

   • Script button opens the boot time script in text editor.

   • Help button opens the Boot time script section of the Handbook.

3. Reports section contains fragmentation report related settings.

   • Options button opens the report options script in text editor.

   • Help button opens the Reports configuring section of the Handbook.

Also UltraDefrag GUI Configurator can be launched from the Start menu. Use Start > Programs > UltraDefrag > Preferences shortcut.
