Duplicate Cleaner has the ability to be easily adapted to display other languages. The language file is in the installed program folder:

 

For example:

C:\Program Files (x86)\Duplicate Cleaner 5\Languages\duplicatecleaner.txd

 

You can use the free TxEditor to edit this language file:

https://unclassified.software/en/source/txtranslation

 

The Wizard translations are in their individual XML files in the Wizard subfolder and can be edited with a text editor.

 

Please feel free to post any new translations to the forum!
