For many, email is the de facto method for sharing files between users. However most email services, including the University’s instance of Microsoft Exchange, impose a limit on the total size of an email, including file attachments. For outlook.unc.edu this limit is 50 MB http://help.unc.edu/help/how-can-i-send-a-large-attachment-over-email/.
There are a few options for transferring files over 50MB.
- Compressing the file may reduce the size enough to include as an email attachment. 7-zip is a powerful compression software for windows that can work with all of the major compression formats http://www.7-zip.org/. On managed Windows computers connected to the AD domain the software can be installed from https://software.ad.unc.edu without admin privilege. Another benefit of this method is that it supports encryption https://itsop.unc.edu/onyen-restricted/procedures/encryption/. This is a good option for external affiliates who do not have outlook.unc.edu accounts to send confidential files as email attachments to unc.edu addresses.
- ITS Research Computing operates a Secure FTP service https://help.unc.edu/help/using-its-research-computings-secure-ftp-server/. You can contact research@unc.edu to have a shared directory created for a set of onyens. Additionally, external affiliates can anonymously upload documents using the procedure described in the document.
