Tips for Sending Large Files

If your attachment exceeds the limits imposed by your email provider, consider these alternatives:

  • Cloud Storage Services: Use Google Drive, OneDrive, Dropbox, or iCloud to store files and share links.

  • File Compression: Use ZIP or RAR formats to reduce file size.

  • Split Files: Break large files into smaller parts using archiving tools.

By understanding the limits and available workarounds, you can ensure smooth file-sharing through email without interruptions.
