Best Practices for Temporary File Sharing
🎯 Choose Appropriate Expiry Times
For sensitive documents, use shorter expiry periods. For collaborative projects, consider longer periods or authenticated uploads.
📝 Use Descriptive Filenames
Make it easy for recipients to identify files. Use names like "contract-v2-final.pdf" instead of "document1.pdf".
🔗 Test Your Links
Always test download links before sharing, especially for important files or when sharing with large groups.
📱 Use QR Codes for Mobile
QR codes are perfect for sharing files with mobile users or when presenting to groups.
📊 Monitor Download Activity
