3. How to restore previous settings after their changes?
First of all, choose those settings which you would like to save, and restart the program. Now you may set all options you want. But it is necessary to uncheck Save settings on exit at Other Options window. After next restart, settings you chose before will be restored. Another way is to save DupKiller settings using File=>Save Settings. And when they must be restored -- File=>Load Settings. Also you can save current settings as user defaults and, when it is needed, restore them. To do it, use corresponding buttons of the Other Options window.

4. How can I print the list of duplicate files?
Current version of DupKiller can not print the list by itself. But you may save the list as HTML-file (execute File=>Save DupFile List and choose Web Page (*.html)) and then print it from browser. Or execute File=>HTML Preview and choose Print in context menu.

5. Can I compare folders using DupKiller?
No, not now. This option is planned to build in the next versions.

6. I can't obviously understand how contents of files are compared. My information of 50GB size has been scanned less than 10 seconds that is physically impossible reading all content of file. This is really doubtful to me.
The point is the program does not always need to read full content of files. When two files are compared, their information is read block by block. Then these little blocks are compared byte-to-byte. At the same time it is counting how many per cent the files are identical. If per cent of difference if more than set one, the comparing process breaks. That is these two files can not belong to the same group.

7. Is it possible to select all of the duplicate files and delete them all?
No, it is made to prevent casual removal of files. But you can use the Autoselect feature to select dupes much faster. Then use the Delete selected files command to remove them.
Top
8. I scanned for duplicate files. Then, a few minutes later, DupKiller found new duplicate files. Does this seem normal?
Yes, if the Use quick comparison option is enabled. In this case you can gain scan time but miss some files. Rescanning may find these files. To find all dupes you need to uncheck Use quick comparison.
Top
9. Does the default settings allow that byte-to-byte comparison of files is enabled (or not)?
No. But you may manually check the Same content option of the Search settings window.
Top
10. How can I adjust the settings for DupKiller, so that byte-to-byte comparison of files is always enabled?
Enable the Same content option from the Search settings window. Then make sure that the Save settings on exit option is checked. Next time you launch DupKiller, your last settings will be restored.

11. Is it possible to pause (hibernate) a scan process in order to resume it next time (when I need to quit program)?
No.
Top
12. How to help the author of DupKiller speed up the program improvement?
Send your program settings file with your question or suggestion or bug report. This will speed up improvement and bug fixes. To save settings, execute File=>Save settings.
Top
13. Can DupKiller search System Hidden folders?
Yes. If a respective option of the Search settings window is checked.

14. How to install additional languages in DupKiller?
To install additional language files, you need to copy the language file to DupKiller folder (for example, C:\Program Files\DupKiller).
Top
15. When trying to install DupKiller, I get the following note (NSIS error message): The installer you are trying to use is corrupted or incomplete. This could be the result of a damaged disk, a failed download or a virus. What is the problem?
This means the installer is corrupted. Probably you have downloaded the DupKiller archive from site incorrectly or incompletely. The only right way is to redownload it again. Also try to use a download manager. It will help you resume downloading in case of its interruption.

No.

17. Is there any version of DupKiller for Linux or other non-Windows systems?
No.

18. I have two .avi files (~700MB) in the same folder. DupKiller does not detect them as duplicate. But another two programs recognizes them as so. Why?
Many programs use comparison with CRC code. So their answer may be just presumable, because they do not compare files entirely. DupKiller uses true byte comparison, and if the files differ even in a single byte, they will not be detected as 100% identical.

19. How can I scan files on remote computer?
To search a remote resource you need to connect it as network drive, so to use drive letters like G:, P:, Y:, etc. UNC-paths are not supported now.
