Sharing Large Files

You can share files up to 250GB  via your OneDrive – upload a file and then share it. You can share your files with school and non-school users (a link will be sent). The link is valid for 30 days when shared outside the school.

For transferring larger files (up to 500GB), we recommend using the FileSender service, operated by CESNET. The service is available at

If the file contains personal information, it is necessary to encrypt it and set up a password before sharing it – for example, you can encrypt a .zip archive using 7-zip.
