Finding specific things
A Smart Folder is a saved question, not a folder. It re-answers itself each time you open it.
File → New Smart Folder, or run any Finder search and click Save.
Set the scope, add criteria with +, then save. It appears in the sidebar and re-evaluates on every open.
Right-click the Smart Folder → Show Search Criteria. The rules reappear and can be changed.
~/Library/Saved Searches
They are .savedSearch files — property lists holding a Spotlight query. They can be copied between Macs.
A Smart Folder is a Spotlight query, so it inherits every Spotlight exclusion. A Smart Folder for "everything over 1 GB" will silently miss large files inside ~/Library, inside packages, and on unmounted drives — which are exactly the places large files hide.
Saved searches in a tool with a complete index do not have that gap, which matters most for precisely this kind of housekeeping query.
Yes. Copy the .savedSearch file from ~/Library/Saved Searches.
No. They store a query, not copies of files.
Everywhere keeps track of every file on your Mac — including the folders Spotlight hides and drives you have unplugged. Free for a day, then $19 once.
