Hello.

I am using version 68.12.1 and the unified folders work fine. I have upgraded to version 91.5.0 (32-bit) and I get this error:

can't open the inbox summary file. maybe there is a disk error, or the full path is too long.

The error appears in English. I don't know if the English translation is exact.

The unified folders look like in the attached image.

I need help, thank you

Highlight the folder, right-click and select 'repair folder' as that normally fixes that.
