Ich kann in der aktuellen Version von AllDup im Kontextmenü keinen Befehl mit dem Namen " Alle Dateien innerhalb der folgenden Ordnerstruktur auswählen " finden. Dort gibts es nur den Befehl " Alle Dateien innerhalb der Ordnerstruktur dieser Datei auswählen " und hierbei bezieht sich die ...

Use the tool wherzit to show the hidden AllDup search result window.

Thank you very much for the information!

With the next update, the old profiles (ANSI) will be automatically converted to the new UTF-16LE format when AllDup starts.

The slow data deletion must be related to the external hard drive you are using.

In a test, we deleted 100,000 files from the search results onto an external USB 3.0 hard drive. The process took only 2 minutes. See log:

Have you tried:

Deactivate the options " Remove groups with only one file ", " Remove files from the search result " and activate "Don't log any file actions (faster)" before you delete all files to speed up the process.


These options exclude the time to update the grid and the logging.

You will have no AllDup-context-menu at the windows explorer. Thats all.

Sorry, but we cant reproduce this problem here using Win11 [Version 10.0.26200.7462].
No crash after a right-click on any of the Windows Libraries or a folder inside a library.

Which version of AllDup do you use?
