New 9 MB Native Mac File Manager Adds Fuzzy Search, Dual‑Pane View and Batch Rename

A developer announced a new macOS file‑manager app on the Hacker News front page, where it quickly gathered 27 up‑votes and 17 comments. The tool was created to streamline the long‑standing problem of a cluttered Downloads folder, offering a lightweight alternative to Finder’s built‑in capabilities.

The application is built with .NET/C# using AppKit and compiled to Native AOT, resulting in a compact 9 MB binary. It provides a range of productivity features: fuzzy “go to” navigation, image/PDF previews on hover, dual‑pane view with tabbed filters, a command palette, batch renaming with regex support, image format conversion, zip creation, bookmarks, Quick Look, single‑click opening, and full keyboard control. File operations are hardened with atomic writes and a manual audit of copy, move, and delete actions. The app maintains a privacy‑first stance, making only a minimal network request to check for updates (omitted entirely in the trial version) and transmitting only the current app version. It runs on Apple Silicon and macOS 12+, offers a 30‑day free trial, and is sold as a one‑time purchase for $19.99, with no subscription model.

The combination of a small footprint, robust file‑handling safeguards, and a suite of quality‑of‑life features positions this tool as a practical option for users seeking a more efficient way to manage files on macOS. The post’s reception on Hacker News suggests that the community sees value in its focused functionality and privacy‑centric design.
