General

• Integrate AllDup into the Windows Explorer context menu
  This option displays AllDup in the Windows Explorer context menu for folders. This allows you to start a search operation by right-clicking on one or more folders. The following additional options can be selected:
  
  • Context menu with Unicode support
    With this option, folders containing Unicode characters in their names can be passed to AllDup and searched. This is the default option used by AllDup.
  • Context menu without Unicode support
    With this option, folders containing Unicode characters in their names cannot be passed to AllDup and searched. Use this option if the first option does not display a context menu in Windows Explorer on your Windows system. This option is not available on Windows 11.
  Using the Register button, you can register the context menu on your Windows system if needed, in case it is not displayed in the Windows Explorer context menu.
• Unicode Text Support
  With this option, Unicode characters from non-Latin script systems are displayed correctly in the search result.
• File Date Display Format
  Here you can define the format in which a file date should be displayed in the search result.
• Storage location for AllDup application data
  This displays the folder where AllDup's application data is stored.
• Folder for temporary files
  Temporary files that need to be unpacked from archives or cached for file preview are created in this folder. All temporary files created after starting the search will be automatically deleted when the search result is closed.
• Exclude from Windows Defender scan
  If you use Windows Defender as an active antivirus scanner on Windows 10/11, you can add file types or folders to its exclusion list here to increase AllDup's operating speed. The excluded file types and folders will then no longer be scanned by Windows Defender, allowing AllDup to examine this data faster and not have to wait for Windows Defender to complete its scan for each file.
  
  • We recommend excluding the storage location of AllDup's application data to avoid delays caused by Windows Defender when accessing working data.
  • If you always compare many image files, you should exclude the various image file types or the entire folder containing the image files.

User Interface

• Toolbars
  Here you can set the design and font size of the toolbars in the program.

  • Groups

  You can edit the color of the objects by setting the font and background color of the user interface to Custom.

Log

• Delete entries from the log file...
  With this option, when an action starts, the log file is checked, and all entries older than the specified number of days are removed.

Search Result

• External program for content comparison of two files
  Here you can define an external comparison program to compare the content of two files. The two marked files in the search result are passed to the external comparison program via the placeholders %1 and %2.
  Example: C:\Tools\Windiff.exe %1 %2
  Placeholders with examples:
  
  • %1 = The complete path of the 1st file (C:\Data\db.txt)
  • %2 = The complete path of the 2nd file (X:\Backup\abc.txt)
  • %3 = The folder of the 1st file (C:\Data)
  • %4 = The folder of the 2nd file (X:\Backup)
  • %5 = The name of the 1st file (db.txt)
  • %6 = The name of the 2nd file (abc.txt)
• Compare the following file types with Microsoft Word
  Here you can specify different file extensions to be opened with Microsoft Word's comparison function. File extensions must be separated by a comma. Example: doc, docx, rtf
• External program for opening folders
  Here you can define an external program for opening folders.
  Example:explorer.exe "%1"
  Placeholders with examples:
  
  • %1 = The complete path of the file (C:\Data\db.txt)
  • %2 = The folder of the file (C:\Data)
• External program for opening files
  Here you can define an external program for opening files.
