This is a test file to demonstrate the PPTX size issue.

If your PPTX file is only 70 bytes, it's likely corrupted or empty.
A normal PowerPoint file should be at least 10KB (10,240 bytes).

To create a proper test file:
1. Open Microsoft PowerPoint
2. Create a new presentation
3. Add title slide: "Test Presentation"
4. Add content slide: "This is sample content for testing PPTX Translator Pro"
5. Add conclusion slide: "Thank you for testing"
6. Save as .pptx format

The resulting file should be 15-50KB in size.

PPTX Translator Pro - Debug Information
Generated: $(date)

System Information:
- Node.js: $(node --version)
- npm: $(npm --version)
- OS: $(uname -s)
- Current directory: $(pwd)

Project Status:
- Dependencies installed: $([ -d "node_modules" ] && echo "YES" || echo "NO")
- Critical packages verified: $([ ${#MISSING_PACKAGES[@]} -eq 0 ] && echo "YES" || echo "NO")

Common Issues and Solutions:

1. "File is too small (70 bytes)":
   - Your PPTX file is corrupted or empty
   - Create a new PPTX with actual content (should be >10KB)
   - Use the "Generate Sample File" button in the app

2. "Module not found" errors:
   - Run: rm -rf node_modules package-lock.json
   - Run: npm install
   - Run: npm install googleapis jszip xml2js pptxgenjs

3. "Google APIs not available":
   - This is NORMAL in development mode
   - App will use mock data for demonstration
   - Real functionality requires Google Cloud setup

4. Translation takes too long:
   - This is normal - Google Translate needs time
   - Mock mode simulates this delay
   - Real translations can take 2-5 minutes

Next Steps:
1. Run: npm run dev
2. Open: http://localhost:3000
3. Generate sample file or create your own PPTX
4. Test the translation process
5. Check browser console (F12) for detailed logs
