FastMediaExplorer

Fast Media Explorer was created to solve a real workflow problem: browsing large media folders quickly.

Implemented now

• Async folder scan (shallow/recursive) + stale-result protection.
• Virtual list view (LVS_OWNERDATA), filtering and sorting.
• Async thumbnails with queue, LRU cache, cancel and throttling.
• Image preview, context menu and keyboard shortcuts.
• Details/Icons view switch + preview panel.
• Drag & drop folder as root and File -> Open folder...
• Filters: name, type, date (including custom range) and presets.
• Duplicate analysis (size-only, exact hash, exact hash + name/ext) + Keep Policy.

Known limits (alpha)

• No persistent on-disk index cache yet.
• No recycle-bin-safe batch delete in duplicate workflow yet.

• Native Windows UI, predictable resource usage, minimal dependencies.
• Core/UI separation + async workflow with generation tokens.
• Viewport-priority thumbnail queue + LRU cache.

• Recycle-bin-safe duplicate batch delete.
• Apply keep policy to all groups.
• Persistent index cache + CSV/JSON export.
