10. File Architect — Create file structures fast

File Architect is a macOS app and a web platform to create and organize file structures via a text editor. Its simple syntax and tab-based nesting system, makes it intuitive, efficient and easy to use.Just outline your desired structure with text and nest with tabs. Hit create, and it’s created on your drive.How it works📁 Folder/File Structure: Lines with dots are files and without are folders. Indent with tabs for nesting.⚙️ Advanced Operations: Additional syntax available for more complex operations. Copy, rename, or move files or folders and their content.🤖 AI Structures: Don’t know how to design a structure? Get an AI-Generated structure from a simple prompt.✅ Valid Blank Files: Files are created as valid blank files that open, not 0 byte stubs.💾 Templates: You can save templates to reuse later.⚡ Fast and minimal: The app doesn’t save anything you create. It’s fast, lightweight (19.9 mb) and simple. Just the necessary and nothing else.💻 Open-Source Engine: Engine behind the app is open-source. You can use it via command-line:https://github.com/filearchitectWhy? Creating file structures on mac is too tedious and starting a new project is always a hassle. Copy an old folder, delete half, still miss stuff or you can hack something together with a couple of shell scripts, but it’s unintuitive and inefficient. I wanted a fast, reliable way to go from outline to structure.Many other features and tweaks are in the roadmap already, but I would love some feedback and suggestions :)
