A new file manager for macOS, dubbed Whim Files, offers a native alternative to Electron-based tools, targeting users frustrated with Finder's limitations. Developed using .NET/C# with AppKit and compiled to Native AOT, the application boasts a compact 9 MB footprint. Key features include real-time filtering by type, date, and size; a fuzzy "Go to Folder/File" function for rapid navigation; dual-pane views; tabs that retain their state; and a command palette for quick access to actions.

Beyond basic file management, Whim Files incorporates batch renaming with regex support, image conversion for formats like HEIC to JPG, and ZIP creation. The developer emphasizes robust file operation handling, employing temporary files and atomic renames to prevent data loss. Privacy is also a consideration, with only an app version check performed for network requests.

The tool ships with a 30-day free trial, followed by a one-time purchase price of $19.99. It requires macOS 12+ and is optimized for Apple Silicon. The focus on native performance and a comprehensive feature set aims to streamline workflows for developers, designers, and power users who manage large numbers of files.

Whim Files represents an effort to provide a performant, feature-rich file management solution without the overhead of cross-platform frameworks. Its small size and focus on core file operations suggest it could appeal to users prioritizing speed and efficiency on macOS.
