Graphical Interface

UltraDefrag GUI is pretty straightforward: you select disks and then either analyze, or defragment, or optimize them. If multiple disks are selected they will be processed one by one. After the job completion you may open a file fragmentation report to check out which files are still fragmented and why.

The program lists all disks available for defragmentation, marked by the following icons:

| Fixed drives
| Removable drives

Criss-crossed icons mark dirty ones. Click Action > Repair drives to clean 'em up.

To select multiple disks use the same rules as in Windows Explorer. For instance, hit Ctrl+A to select them all.

Double-click a drive or select it and hit Enter to start its analysis (repair if it's a dirty one).

# Cluster map

The bottom part of the window shows the cluster map of the selected disk. It represents disk clusters by little colored squares. The top left square represents the first cluster, the bottom right - the last one. All the clusters in between are organized by rows. The colors have the following meaning:

| Fragmented |  |  | Not fragmented |  |  | Compressed
| Directory |  |  | Locked (system) |  |  | MFT
| Free space |  |  |  |  |  | Unused map cell

Files and directories
  When there are two different colors assigned to the same item, the darker one marks objects above the size threshold, if one is set.

MFT
  Dark magenta represents the master file table (MFT), light magenta - the space reserved for its expansion.

Unused map cells
  Each cell reflects an integer number of clusters. So, for instance, if a disk has 1000 clusters, but its map contains a bit more cells those redundand cells will be not used at all. On the other hand, if the map has exactly 2000 cells they will be all in use, reflecting 2 clusters each.

Note
  Unused map cells are not to be confused with free space.

Free space color
  The default is white as shown above, but it can be changed through a background color option.

It does make sense to set grid_line_width = 0 if you set map_block_size = 1 to use the screen space more efficiently. This is especially useful, if you have drives bigger than 500GB in size. To set both options click Settings > Options and edit the appropriate lines in the opened configuration file.

# Menu

## Action

| Analyze (F5; Enter) Analyze the selected disk(s).
| Defragment (F6) Defragment the selected disk(s).
| Quick optimization (F7) Perform quick optimization of the selected disk(s).
| Full optimization (Ctrl+F7) Perform full optimization of the selected disk(s).
| Optimize MFT (Shift+F7) Optimize the master file table on the selected disk(s).
| Pause (Space) Pause or resume the job. The current file movement will be completed to avoid data corruption.
| Stop (Ctrl+C) Abort the job. The current file movement will be completed to avoid data corruption.
| Show report (F8) Open the file fragmentation report for the selected disk(s).
| Skip removable media (Ctrl+M) Exclude removable drives from the list.
| Rescan drives (Ctrl+D) Update the list of drives.
| Repair drives Repair the selected disk(s) using the chkdsk command line tool.
| When done Set the action to be performed after the job completion. The default is None, available actions are: Exit, Standby, Hibernate, Logoff, Reboot and Shutdown. Note To shut the computer down successfully both your system and hardware configuration must support shutdown and power off, otherwise Windows might either reboot the computer or simply stay idle. The same way neither standby nor hibernation will work when they aren't supported by the hardware or aren't turned on in Windows.
| Exit (Alt+F4) Terminate UltraDefrag.
