Delete all keywords

[frankdarwin]

Hello,
is it possible to delete all keywords of all photos at once?
I have not found anything in the help.

See The Menu and "Delete all keywords" in Frequent Tasks.
Tip: This was quickly found by searching (Ctrl+F) for delete all keywords in the Keyword Panel topic.

Alternatively, you can just enable Using the Full Edit Mode and <Ctrl>+<A> and <Del>, whatever you prefer.

Thanks for the quick reply.
But unfortunately it does not work the way I want it to.
I want to delete all keywords of all photos in the test database (4375). So all keywords in the database.

To do this I select all the photos and try to delete the keywords as you suggested.
Then I get the message "Too many files selected" (See attachment).

How many photos can I select so that it works?
Is there another way?

This will still work. But the panel will not attempt to merge the keywords of all files selected.
You can also delete the keywords of all selected files in the Metadata Panel. Or use a Metadata Template. Or use the Metadata Mechanic app. So many ways to do this. Takes only a few seconds.
Metadata Mechanic can only update tags with non-empty values. My mistake, sorry.

Another option - go to the Categories panel, select all the child keywords below the @keywords category, right-click and select 'Delete' while holding down the CTRL key.
