Solution:
Try opening the file on your computer to verify it's not corrupted
Re-download the original file if you received it via email
Save a fresh copy from the source application
Network Timeout
Error Message: "Upload failed" or "Connection timeout"
Solution:
Check your internet connection
Try uploading again
If on a slow connection, upload smaller files first

Use descriptive filenames: Name files clearly (e.g., "Technical_Requirements_Section_3.pdf")
Organize before uploading: Group related files together
Check file quality: Ensure PDFs are searchable (not scanned images)
Upload in batches: For large projects, upload files in logical groups
