• Confirm that returning 0 for cases where columns is 0 is the desired behavior for downstream layout calculations; adding a clarifying comment may help future maintainability.

return columns > 0 ? (containerWidth / columns) - itemMargin.Left - itemMargin.Right : 0;

src/Files.App.Controls/AdaptiveGridView/AdaptiveGridView.Properties.cs:155

• Consider explicitly handling cases where itemWidth is negative by checking for itemWidth <= 0 to strengthen the robustness of the calculation.

var columns = itemWidth > 0 ? (int)Math.Round(containerWidth / itemWidth) : 0;
