Imports All editions

Each Imports node is one folder watched/scanned into your database. This is where libraries come from.

Imports node

Imports are subdivided sections of your database. Every folder or group of files you drag to the Results List or import with Ctrl+I / Cmd+I creates an Import. Some editions can rescan or merge them.

You can Explode Folders to see every folder structure inside an Import. Ctrl / Cmd + click any folder to create a Filter Block to search against.

Click the left-side icon next to any Import to bring it In or Out of searches. If your edition supports it, you can Rescan to update for changes.

How Exploded folders work. If a folder hasn’t been imported or rescanned into the database, you’ll see it but clicking it won’t show records — basehead only shows results that exist in the DB. Rescan the Import after making changes outside basehead.

Folder Blocks

Folder Blocks pinned to the search bar

Ctrl/Cmd+click any exploded folder to spin it into a Folder Block — a search-bar pill that scopes results to just that folder. Stack multiple folder blocks to search across several at once.

Auto-Rescan with the Watcher

Keeps each Import in sync with your filesystem. The rescan runs at app shutdown — not continuously — and reports anything that needed attention on the next launch.

Watch Level Standard, Ultra

Click the flyout button on an Import row, or right-click → Watch Level:

OffAuto-Rescan disabled.
LowRescan when ≥ 10% of files have changed.
Medium≥ 5% change.
High≥ 1% change.
MaximumAny single file change triggers a rescan.

Root-menu rescans

Right-click the root Imports node:

Rescan All Imports PremiumEvery Import, regardless of Watch Level.
Rescan Watched Imports Standard, UltraOnly Imports with a Watch Level set.

Deletion-cap safety net

Watch Level decides when a rescan runs — it doesn’t decide how many deletions get applied. That’s a separate safety net, the same at every level:

5% capMore than 5% of files missing → deletions skipped, flyout asks before anything is removed.
50% capMore than half missing → rescan aborts entirely. Almost always a missing volume or dropped network share.

Aborted rescans show a flyout on next launch with the Import name, missing-file count, and cap. Click Rescan to retry.
