Comprehensive metadata extraction and analysis from various file types.
When to Use
- Metadata extraction requests
- EXIF data from images
- Document properties analysis
- Keywords: "metadata", "EXIF", "file properties", "document info"
Core Capabilities
1. Image Metadata (EXIF)
- Camera settings, GPS coordinates
- Timestamps, camera model
- Software, copyright info
2. Document Metadata
- Author, title, keywords
- Creation/modification dates
- Edit history, hidden data
3. File System Metadata
- Timestamps (created/modified/accessed)
- Size, permissions, owner
- Extended attributes
4. Media Metadata
- Audio: Artist, album, bitrate
- Video: Codec, resolution, duration
Quick Reference
ExifTool Commands
# View all metadata
exiftool file.jpg
# Extract specific tags
exiftool -Title -Author document.pdf
# Remove all metadata
exiftool -all= file.jpg
# Batch extract to CSV
exiftool -csv -r /path/to/images > metadata.csv
# Extract GPS
exiftool -gps:all image.jpg
Other Tools
# Image (ImageMagick)
identify -verbose image.jpg
# PDF
pdfinfo document.pdf
# Audio/Video
mediainfo video.mp4
ffprobe -show_format audio.mp3
# File system
stat file.txt
Privacy Concerns
Sensitive Metadata:
- GPS coordinates (location)
- Author names (identity)
- Device serial numbers
- Edit timestamps
Removal:
# Remove all
exiftool -all= image.jpg
# Remove GPS only
exiftool -gps:all= image.jpg
Use Cases
- Photo Organization: GPS/timestamp for sorting
- Digital Forensics: Authorship, timeline
- Copyright Verification: Author info
- Data Privacy: Remove sensitive metadata
- Asset Management: Cataloging
Output Format
- File Info: Path, type, size
- Basic Metadata: Date, author, title
- Technical: Format, dimensions
- Privacy Concerns: Sensitive data detected
- Recommendations: Actions to take
Integration
- digital-forensics: Timeline reconstruction
- file-organization: Auto-categorization
