- Frequently Asked Questions
-
- 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.: How can I disable boot time defragmenter manually?
-
- A.: If something is wrong and boot-off script does not work properly, remove
- the defrag_native entry from the following Registry parameter manually:
-
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\BootExecute
-
- 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:
- 1. Open a command line with admin-rights:
- Start -> execute -> CMD (with admin rights).
- 2. Type:
- bcdedit /set loadoptions "DDISABLE_INTEGRITY_CHECKS"
- bcdedit /set nointegritychecks ON
- 3. Close the command prompt and start group policy editor:
- Start -> execute -> gpedit.msc
- 4. Go to:
- User Configuration -> Administrative Templates -> System ->
- Driver Installation -> Code Signing for device drivers
- 5. Enable this policy and set it to Ignore state.
-
- 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 the
- 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 dedragmented. You may specify sizes with the following
- suffixes: (Kb | Mb | Gb | Tb).
