Everytime you run analyze, compact or defragment, a report of all fragmented files on the file system is created. Objects excluded from the defragmentation process are marked by black color. The report has the following fields:

1. Number of fragments.
2. Filename
3. Comment - can be blank or contain one of three values:
   • [OVR] File is above the size threshold.
   • [DIR] Object is a directory.
   • [CMP] Compressed file.

To change items sorting click top link on the preferred column. Note that it's a slow process - about 1.5 seconds for 550 items on 1.8GHz CPU. Sorting implemented in JavaScript is slow, but very reliable.

To open the file fragmentation report click Fragmented button in GUI application. Also you can view these reports outside the GUI program: just click fraglist.luar icon in Explorer. You will find these files in root directory of each analysed volume.

File fragmentation report options are stored in udreportopts.lua file located in %windir%\UltraDefrag\options directory. This is just a simple text file (in ANSI encoding) with comments and parameter-value pairs. However it's a real program written in Lua language.

The strings with -- character sequence in the beginning are comments. Here is a complete example:

]]

To edit these options, click Edit report options button in Settings window of GUI interface or use the appropriate shortcut in Start > Programs > UltraDefrag > Preferences menu.

If you have problems with configuration files editing, use the following menu in Explorer Tools > Folder options > File types and associate lua extension with your preferred text editor.
