Font Forum

I have a very large number of fonts. The library is showing around 18,000 fonts but I have imported a group with various subfolders that contains 30,000. If I search for duplicate fonts is shows 920 selected but only a very few of the first fonts alphabetically are highlighted.
Why are the numbers as they are?
Can I show just the duplicate fonts?
Why aren't all the duplicate fonts highlighted?

Do you search for duplicates while the Library view is active?

Yes. It shows 1021 selected but only 1 font family with about 30 duplicates is blue.

It is good to know that MainType is a font manager, not a file manager. It collects all unique fonts, so an exact copy of a font file is not considered a duplicate. In MainType only unique fonts are shown, exact copies are shown in the Resources section of the Information panel.

In case you have 3 font folders with these fonts:

Folder A
MyFont version 1
MyFont version 2
MyFont version 3

Folder B
MyFont version 1
MyFont version 3
MyFont version 4

Folder B
MyFont version 1
MyFont version 2
MyFont version 5

Then MainType will show these fonts:
MyFont version 1 (3 resources)
MyFont version 2 (2 resources)
MyFont version 3 (2 resources)
MyFont version 4
MyFont version 5

And Select Duplicates should select all but the last version of MyFont.

But that does not explain when I chose Select Duplicates, at the bottom of the screen it shows '1021 fonts selected' but only around 30 are actually selected. So what does the 1021 figure represent?

A screenshot might reveal the issue.

Is the view in Font Family mode?

Here's a screenshot

Also solved by uninstall including cache and database and reinstall. Now highlighting all duplicates.

The screenshot shows you are in family mode.
