🚀 [Latest Update: v4.1.1]
Ultra-lightweight optimization & Enterprise-scale (Massive Drive) support!
• We completely overhauled the background auto-save process using a "proprietary array compression algorithm." Even when running global scans on massive drives (1TB+, 300,000+ folders, millions of files), it completely eliminates browser freezing and high CPU usage/fan noise.
• Introduced "Fast Path" rendering to eliminate UI lag (sluggishness) when hovering over items or navigating folders. Everyday usage is now incredibly smooth.
• Optimized API load balancing during continuous data fetching to reduce network errors during deep scans.
💼 Perfect For:
• Engineers & Creators: Quickly locate and archive heavy past projects, including large 3D CAD files, high-res images, and raw videos.
• Shared Drive Administrators: When Workspace team storage nears its limit, visualize exactly which department or folder is responsible, and encourage better data management.
• Personal Users: Clean up your digital clutter by organizing smartphone backups and deleting forgotten data from years ago.
✅ How to Use (It's incredibly easy):
1. Install this Chrome extension.
2. Open Google Drive (drive.google.com).
3. Grant access with a single click.
4. That's it! Folder sizes will automatically appear next to your folders.
🔒 Privacy and Security First:
We fully understand that your files are private and highly confidential.
• Read-Only Access: Drive Size Pro operates strictly on "read-only" permissions. It absolutely cannot modify, move, or delete your files.
• 100% Local Processing: All data analysis happens securely within your own browser (locally). Your data is NEVER sent to external servers or third parties.
