GNOME Tracker Cache
GNOME Tracker’s cache under ~/.cache/tracker3 stores extracted file metadata, full-text indexing fragments, thumbnails, and SQLite support files used by the Tracker miners and search service to speed up GNOME Shell search and file lookups. Those caches are rebuilt from your actual files and database state, but stale thumbnail entries, fragmented SQLite pages, and leftover miner cache data can make indexing slower or search results inconsistent. Kudu removes only the rebuildable Tracker cache files so the indexer can recreate them without touching your documents, settings, accounts, or passwords.
Why clean GNOME Tracker Cache?
- Stale extracted metadata after large file moves or renames can leave GNOME Shell search showing old paths or duplicate results until Tracker rebuilds its cache
- Corrupted thumbnail and preview cache entries cause missing or incorrect file previews in search and file pickers even though the original files are intact
- Fragmented SQLite cache pages make Tracker read and rewrite more data than necessary, so searches feel sluggish and disk activity spikes; VACUUM rewrites the database file without deleting your indexed content
- Interrupted indexing jobs can leave partial cache state behind, leading to search results that appear incomplete until the miner rescans the affected folders
- Very large caches from years of indexing consume unnecessary space in ~/.cache, which users notice as growing home-directory usage despite not adding many new files
- Old full-text indexing fragments can make newly edited document contents fail to appear in search right away, or cause searches to match outdated text snippets
- After Tracker package upgrades or miner crashes, incompatible cache artifacts can trigger repeated reindex attempts, high CPU usage, and constant background disk access
