Kleaner PRO 11.1: Faster Scanning and Leaner Reports

Scanning: reuse what did not change, walk in parallel

The engine now remembers its previous pass. A file whose size and modification time have not moved since the last scan keeps its verdict — nothing is re-read from scratch, and only what actually changed gets a fresh look. Independent locations are walked in parallel instead of one queue, so a slow OneDrive folder no longer holds up the whole scan. On our test machines, a re-scan that took about a minute in 11.0 now finishes in roughly half that; a first scan, where there is nothing to reuse, is a few percent quicker.

Nothing about targets changed: the same allowlist, the same junction awareness, the same refusal to touch anything a Windows subsystem has not declared disposable. If a folder gains new files, they are scanned as new — cache or no cache. That is the whole speed story: reading less, not checking less.

Reports: a decision layer first, details on demand

The old report laid every category out in full detail on one level, which was honest and exhausting. 11.1 leads with the part you act on: total reclaimable space, the top categories by size, and anything unusual flagged in plain language. The full per-category breakdown is still there — one click deeper, not removed. The exported report is shorter too, carrying the summary plus the categories you selected rather than everything by default.

Grouping also got smarter: the same cache reachable via two paths is now one row with one byte count, not two entries arguing over the same space. Duplicate rows are noise, and noise is what makes people stop reading reports. Fewer lines, better sentences, same numbers underneath.

• Opens with total reclaimable space and the top categories by size
• Anything unusual — a cache grown abnormally large — is flagged in plain language
• The full per-category breakdown sits one click deeper, not removed
• The same cache reachable via two paths is merged into one row with one byte count
• Exports carry the summary plus the categories you selected, not everything by default

Rollout, and what is next

11.1 is a free update for every 11.0 license, offered through the built-in updater; installation takes under a minute and preserves your settings. Scan history is preserved as well, so the first run after updating can lean on the cache left by your last 11.0 scan. Next on the list is the same discipline applied to the rest of the app — boring, honest, and worth it.
