How to select only files into an Active filter?

[enircwe]

Hello, I would like to, after applying the "files ranging in size from 20 to 50 MB" filter, select only 1 duplicate file from the entire duplicate list that is shown to me with the active filter.
I have tried but it doesn't work, after activating the filter, the tool for selecting the files also selects the unfiltered files. How can I resolve this?

I want to select 1 of the 2 duplicate files only from the active filter, not the duplicate files not shown by the filter, is that possible? Have I explained myself?

If the active filter only shows 2 duplicate files and I select only 1 of the 2 files with the "assistant menu", it also selects those not shown by the filter, and I don't want that.

Which Selection Assistant function are you using to mark?

Are you sure you are using the 'File sizes between..size' filter and not the 'Groups between...size' filter?

Thanks ! You are right! Now works, which is the differences?

"Group sizes" filters by the total file size of the group
