Storage Health
FlashBoards stores board data and media locally in the browser. The Storage Health tab helps you understand storage pressure, find broken board references, and clean safe-to-remove local data.
How To Access
Open Settings (gear icon) and select the Health tab in the sidebar.
What It Shows
- 1localStorage — Board data, settings, models, and workflows. Limited to ~5 MB by the browser.
- 2IndexedDB — Media blobs, image cache, and video thumbnails. Much larger limit (typically hundreds of MB to several GB).
- 3Per-board usage — Expand to see how much media each board consumes. Computed on-demand.
- 4localStorage Analyzer — Scans board data for empty media tiles, missing saved-media records, duplicate IDs, and broken nested media links.
- 5Memory caches — In-memory caches for images, video thumbnails, and audio waveforms. Cleared on page reload.
Broken Library Items
If a board tile points to a saved file that is already missing, Health can prepare a manual cleanup. It removes broken empty tiles and clears broken nested links from otherwise healthy items.
This does not delete real media files. FlashBoards asks for confirmation, blocks cleanup while boards are still loading or a generation is running, and tries to save a local rollback backup before applying changes.
Orphan Analyzer
Over time, media blobs can become orphaned — stored in IndexedDB but no longer referenced by any board. This can happen when you delete items or after failed generations.
Click Analyze to find orphaned blobs, then Clean Up to delete them and free space. The analyzer re-checks references before deleting to prevent accidental data loss.
Quick Actions
- 1Clear Image Cache — Frees memory from cached browser images. Images will reload from IndexedDB as needed.
- 2Clear Thumbnails — Removes cached video thumbnails from IndexedDB. Thumbnails will regenerate on next view.
- 3Clean Broken Library Items — Removes only board entries whose local files are already missing, after an analyzer pass and confirmation.
When Storage Is Still Full
Health can show trash, cache, orphan, and broken-link cleanup options, but it may not always find enough safe data to remove. If storage is already full, export old boards first, then delete unused boards or large media from your workspace to free space manually.
The Boards menu also shows a warning when browser storage is near the same limits used by Health. Treat it as a signal to back up and reduce storage before importing more media.
