Smart Size Explorer adds a dedicated Explorer view that shows the size of files and folders in your workspace, along with detailed file and folder counts.
It is designed for real-world projects, including large repositories and monorepos, with a focus on performance, stability, and usability.
✨ Features
- 📁 View file and folder sizes in a custom Explorer panel
- 🔢 NEW: File and folder counting - See the exact number of files and subfolders in each directory
- Tree view displays:
folder-name • 15 items (10 files, 5 folders) - 1.2 MB
- Status bar shows counts for active folders
- Enhanced tooltips with complete breakdowns
- ⚡ Fully async and non-blocking (no UI freezes)
- 🔄 Live updates on file system changes
- 📊 Sort items by size (largest first)
- 🧠 Smart caching with configurable TTL (caches both sizes and counts)
- 🚫 Optional inclusion of
node_modules
- 🛡️ Safe handling of permission errors and broken symlinks
📊 What's New - File and Folder Counting
Smart Size Explorer now shows you exactly how many files and folders are inside each directory:
Tree View Display:
📁 src • 127 items (95 files, 32 folders) - 2.4 MB
📁 node_modules • 8,542 items (7,891 files, 651 folders) - 156.3 MB
📄 README.md - 4.2 KB
Status Bar:
- When you open a folder:
📁 2.4 MB • 127 items
- When you open a file:
📄 4.2 KB
Enhanced Tooltips:
Hover over any folder to see:
- Total size
- Number of files
- Number of folders
- Total items count
Performance:
- Counts are calculated during the same recursive traversal as sizes
- Results are cached together (no extra overhead)
- Updates automatically when files are added/removed
⚙️ Configuration
Open Settings → Smart Size Explorer:
smartSizeExplorer.showNodeModules
Show or hide the node_modules folder size (disabled by default)
smartSizeExplorer.sortBySize
Sort files and folders by size (largest first)
smartSizeExplorer.cacheTTL
Cache duration (in milliseconds) for folder size calculations
🚀 Why Smart Size Explorer?
Most file explorers don’t show folder sizes or struggle with large projects.
Smart Size Explorer is built with production-grade performance and clean architecture, making it reliable even for very large codebases.
📌 Notes
- The VS Code API does not allow modifying the default Explorer tree.
- This extension uses a dedicated Explorer view, which is the officially supported approach.
