VirtualTabs – VS Code Extension for Virtual Tabs & Custom File Grouping

繁體中文 | English

🚀 What is VirtualTabs?

VirtualTabs is a VS Code extension that provides custom "Virtual File Directories" outside of your native file system. Unlike standard directories, VirtualTabs helps you create independent logical file groups based on your current development theme, while also providing AI-Ready Coding Context for quick copying. It is perfectly suited for Monorepo projects or large-scale applications using MVVM or MVC architectures.

⚡ VirtualTabs vs. Native VS Code Tabs

🧩 Solving Modern Workflow Pain Points

In MVC/MVVM or large-scale projects, related files are often scattered across deep directory structures, making switching a repetitive chore:

❌ Traditional File Structure:
├── config.json          (Root Config)
├── styles/theme.css     (Style Layer)
├── src/components/      (View Layer)
├── tests/__tests__/     (Testing Layer)

✅ Theme-Based Virtual Directory:
📁 Feature: Theme System
  ├── 📁📚 Configuration
  │   └── config.json
  ├── 📁📚 Style Definitions
  │   └── theme.css
  ├── 📁📚 Components (View Layer)
  │   └── ThemeProvider.tsx
  │     └── 🔖 Line 45: Context setup
  └── 📁📚 Unit Tests (Logic/Testing)
  │   └── theme.test.ts

🤖 Born for AI Collaboration

In the era of Copilot and LLMs, precise context is the key to high-quality results:

• Curated Selection: Create groups with only the files relevant to your current task.
• One-Click Export: Convert entire groups into AI-friendly Markdown blocks (v0.3.0).
• Reduced Noise: Isolate core logic to help AI focus and prevent hallucinations.
• Persistent Context: Your curated AI prompts and file sets stay ready even after a restart.

"VirtualTabs helps me define the exact boundary of what the AI should see."

❓ FAQ

Q1: I don't see the VirtualTabs panel?

Check:

• The extension is enabled
• Your VS Code version is 1.75+
• VirtualTabs has its own icon in the Activity Bar (left sidebar)

Q2: How do I create sub-groups?

Right-click any group → Add Sub-Group. You can also drag a group onto another group to nest it.

Q3: How does "Copy Context for AI" work?

It reads all files in the group (including sub-groups), formats them as markdown code blocks, and copies to clipboard. Binary files are automatically skipped.

Q4: Can I share my groups with my team?

Currently, groups are saved in workspaceState (local) or .vscode/virtualTab.json (shareable). v0.3.2 introduced support for .vscode storage!

Q5: Do bookmarks work across file renames?

Yes! Bookmarks track file paths and will update if you rename files within VS Code.

Q6: How do I drag folders into groups?

Simply drag a folder from the Explorer panel onto a group. VirtualTabs will automatically add all files recursively, skipping the directory entry itself.
