Filter a long folder in place
View ▸ Filter Current Folder narrows what's already listed, without a search across subfolders.
How to do it
- Open a folder with many items.
- Choose View ▸ Filter Current Folder.
- Type part of a name: the listing narrows to matching items already in this folder.
- Nothing inside subfolders is searched, so it is instant. Use ⌘F when you want to search across folders.
