- Apache POI (for MS Office tests)
- Apache Commons Compress (for archive tests)

### Test Resources:
- `extractor/msoffice/test.doc`
- `extractor/msoffice/test.xls`
- `extractor/msoffice/test.ppt`
- `extractor/test.txt`
- `extractor/zip/test.zip`

## Key Improvements Tested

### 1. Resource Management
- ✅ Try-with-resources usage in MS Office extractors
- ✅ Proper closure of POI objects
