# Filelink via Nextcloud

**Filelink via Nextcloud** is a method of sending large files via email by replacing physical attachments with cloud-based download links.

## Purpose
This approach is used to:
- Avoid exceeding the maximum attachment size limits imposed by email servers.
- Reduce the storage burden on the recipient's mailbox.
- Provide a more secure and manageable way to share large datasets or documents.

## Implementation
At the Universität Greifswald, this is implemented using the [[nc-connector]] extension for [[mozilla-thunderbird]]. The process is automated so that files exceeding a specific size threshold are uploaded to the university's [[nextcloud]] instance, and the resulting URL is inserted directly into the email composition.
