Cannot find Duplicate File Finder

The manual says FIND DUPLICATE FILES is under the TOOLS menu.
The only FIND I have is the CONTROL F find which brings up a Find utility panel.
I cannot find the DUPLICATE FILE FINDER ...
Am I missing something?

Are you using Light or Pro? Please link your account.

HI -- I am using LIGHT.

The Duplicate File finder is only in the Pro version:

Thanks for the explanation.
Suggestion: shouldn't we then have two different HELP files? Or at least an indication of which features are in which version?
It will save a lot of time . . .
