Does Everything track any indexing on how many files and folders that a folder contains, to speed up the processing of childcount:<count>, childfilecount:<count>, childfoldercount:<n>, empty:, or are these calculated on demand?
Everything keeps the childcount: property for all folders.
childfilecount: and childfoldercount: are calculated on demand.
For childfilecount:, I calculate (childcount: - childfoldercount:) as this is faster.
Since childfilecount: and childfoldercount: are calculated at the time of your search they may become out of date.
If these counts are being indexed, can we get a column(s) for them?
Yes, columns for these properties are in development.
I will also be using a new method to instantly calculate childcount:, childfilecount: and childfoldercount:.
The childcount: property will no longer be stored for folders.
This will make your Everything database slightly smaller.
The results from childcount:, childfilecount:, childfoldercount: and empty: will also be live (always up to date).
Thank you for your suggestions.
