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?
Thanks

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

HI -- I am using LIGHT.
Thanks

The Duplicate File finder is only in the Pro version: https://www.gpsoft.com.au/program/pro-lite.html

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 . . .
Thanks
