SimpleFiles 1.1.5.0

SimpleFiles is a file manager designed for Windows 11 that emphasizes native integration, responsive performance, and a compact runtime footprint. Built with WinUI 3 and Mica materials on .NET 10, it is packaged as a self-contained desktop utility intended to avoid external runtimes, web wrappers, or background telemetry.

Performance and compatibility are central to the design: the app is delivered in native x64 and ARM64 builds, targets a low idle memory profile (around 50–60 MB), and focuses on fast cold starts and minimal disk impact.

• Navigation: Dual browsing modes combine traditional hierarchical drive views with virtual category aggregations for photos, documents, and videos. Interactive breadcrumbs and high-resolution file tiles provide quick orientation and visual previews with Fluent-style glyph fallbacks for non-media files.
• QuickPeek: A spacebar-activated preview canvas supports a broad set of formats across images, audio/video, and developer text files. It offers variable playback speeds (0.25×–3.0×) with presets and fine-grain controls, fullscreen playback, and auto-hiding transport controls for an unobstructed preview experience.
• Security Vault: An encrypted container uses AES-256 CBC with PBKDF2 HMAC-SHA256 key derivation (100,000 iterations) and ties keys to the Windows Credential Locker. Features include a decoy vault for plausible deniability, in-memory previewing of encrypted items to avoid unencrypted disk artifacts, and random-access cryptographic streaming for seeking in encrypted media.
• Storage tools: Cleanup diagnostics surface installer files, large files over configurable thresholds, and duplicates. The duplicate finder groups files by exact size and verifies matches using chunked SHA-256 hashing. System temp and Recycle Bin purging are included as one-click actions.
• Power-user ergonomics: Native keyboard accelerators align with standard Windows shortcuts, Win32 Shell integration preserves undo behavior for Recycle Bin operations while offering one-click permanent deletion, and an intelligent collision resolver manages copy conflicts. A properties inspector exposes byte-accurate sizes, metadata, and basic attribute toggles.
