How does Mail Drop help a user when sending large files?

Mail Drop is a feature in Apple's Mail application that facilitates the sending of large files by allowing users to send files via email without being constrained by size limitations typically imposed by email servers. When a user attaches a file that exceeds the standard email attachment size limit, Mail Drop automatically uploads the file to iCloud and includes a download link in the email. This enables the recipient to download the file from iCloud, thereby bypassing the usual attachment size restrictions.

This functionality is especially useful for collaborating on projects that may involve large multimedia files, such as videos or high-resolution images, which often exceed the size limits set by many email providers. By leveraging iCloud storage, Mail Drop ensures that users can share substantial files seamlessly, enhancing the efficiency of email communication.

The other options do not accurately describe the primary function of Mail Drop: it does not involve file compression, format conversion, or encryption of attachments. Instead, it focuses on managing file size limitations by utilizing cloud storage for larger files.
