| Q.: | Why configuration files editing is better than settings window with tabs? |
| A.: | This way is more reliable. The settings window was nothing more than a
specialized editor. But we have thousands of free universal text editors
including standard Notepad. Use your favorite text editor for configuration
editing and enjoy! They were removed few hundred lines of source code related to old settings window. Less code we have less bugs we have!! |
| Q.: | Why UD doesn't work on x64 Vista with Service Pack 1? |
| A.: | This version of Windows needs driver signature (from Microsoft) to load program's
engine. Bill Gates thinks that you are so stupid that you can't decide,
load the driver without signature or not. Therefore you can't allow that
though you are a system administrator and maybe payed few hunreds of dollars
for a Windows license. THE DRIVER SIGNATURE IS COMPLETELY INCOMPATIBLE WITH GPL!!! Because we need a new signature for each new build. Therefore I will never try to get them for UD driver. |
| Q.: | I've seen message "Can't load ultradfg driver!" on Windows Vista. I think that Vista is preventing this driver from loading because the signature check is enabled. How can I disable it? |
| A.: | Thanks to Christopher Naegel for providing
the following instructions:

| Q.: | How many differencies are between the Ultra Defragmenter and well known JkDefrag application? |
| A.: |
Analysis algorithm is generally the same. But defragmentation is done in
different ways. JkDefrag tries to optimize files placement using original
algorithm that is complex enough. On the other hand, Ultra Defragmenter is
simple as possible - it tries to move all fragmented files to free space areas.
Nothing more. 'Compact' option was added to give you an ability to move all
files to the beginning of the volume to enlarge free space areas for future
defragmentation success. The best advantages of the Ultra Defragmenter are an ability to defragment system files at boot time and well readable reports. Also our program has a nice GUI that is very important for many peoples. At the same time advanced users can use console interface that is a little bit faster because don't use any cluster map representation. The main disadvantage of both applications (Ultra Defragmenter and JkDefrag) is that they are based on MS defragmenting interface that has very ugly implementation. We can't change it's behavior because it's a part of filesystem drivers (ntfs.sys, fastfat.sys) that are too complex and not open source to modify or replace them. |
| Q.: | How can I use filters? |
| A.: | The include field is where you enter substring expressions that match file names (incl. path) that you want to defragment. And the exclude field expressions disable defragmentation of matching files. You can enter multiple expressions, separating each with a semicolon (;). The next field in the form is captioned 'Ignore files greater than.' Files over this size are not defragmented. You may specify sizes with the following suffixes: (Kb | Mb | Gb | Tb). |
| Q.: | The progress bar updates irregularally. Why is this? |
| A.: | The
progress bar measures disk space, not the number of files. So when few
big files are analysed, the progress bar will increase very fast.
Conversely, when a thousands of small files are analysed, progress will
be relatively slow. Example: You have 1x100 Mb + 1000x100kb files. Let us assume that we need 10 msec per file and a big file is in the root directory placed. In this instance, progress will be at the 50% point after 10 msec, but at the 100% point after 10 sec. |
