v1.1 — What is this?

What's new in v1.1 — "What is this?"

Ordinary users often have no idea what half the programs living in their
Temp/AppData folders actually are. Now the cleaner can tell you:

• Right-click any row -> "What is this?" — for known programs your
  default browser opens the vendor's official page (offline knowledge
  base with 66 curated entries, every URL verified). For unknown ones —
  a Google search with just the program's name.
• Privacy by design: only the program/vendor folder name goes into
  the search query — never the full path, never your username. The
  network is used only when you explicitly click.
• The same menu also offers Copy path and Open folder.
• One exe for both languages — the UI language (English / Lithuanian)
  now switches inside the app; first run follows your Windows language.
• "?" help corner — About dialog and an in-app user guide, including
  "Ask the AI that wrote it" instructions.

Nothing else changed — scanning, preview, cleaning and all safety guards
(AGE / LOCKED / JUNCTION) are untouched and covered by the same test
suite (now 31 new unit tests + live GUI test on a synthetic tree).

Also new in the repository: docs/COMPARISON_TEST.md —
a reproducible live comparison protocol vs Storage Sense and CCleaner,
including the points where they win.

Idea credit: Robertas — born from watching real users squint at yellow
rows. Built, tested and documented by Claude.

Temp Cleaner v1.0

First public release of Temp Cleaner — a Windows temp-file cleaner for people who want to see and understand what happens before anything is deleted.

Highlights

• Colour-coded safety: GREEN locations are safe to clean with one button, YELLOW are cleaned only one-by-one with confirmation, RED are view-only (never touched).
• Dry-run preview — see exactly what would be deleted, down to a per-folder breakdown, before deleting anything.
• Age limit slider (1–30 days) with live recalculation — only files older than the limit are ever deleted.
• Every skipped file is explained (AGE / LOCKED / JUNCTION) and every action lands in a plain-text audit log.
• Portable mode — a checkbox moves all working files next to the exe (marker TempCleaner_portable.txt), leaving no traces on the computer.
• LT / EN switchable in-app (one exe); plain-text guides also in Russian.
• No ads, no telemetry, no network access. Open source, MIT.
