Have you ever struggled to share large files with your colleagues/external parties?
Sending large files through email may not be the best solution. In general, all email service providers have set a limit to the maximum email size that an email can be received/sent out due to security reasons. For our staff email server, it allows incoming and outgoing messages up to 40 MB in size. The most popular email clients (e.g. Gmail or Yahoo) limit the attachment file size to 25 MB. Any message larger than the size is rejected. As a result, it is difficult to share large files via email.
In addition to email, ICTO offers more options for you to share large size of files or videos with others in a secure and efficient way.
The suitable option for file/ video sharing depends on the following factors:
- Size of the file
- Target recipient (University member/ external party)
- Type of the file
- Location for accessing the file (On/ off campus)
