You can still get access to your storage while you are working from home or anywhere else off-campus. How you do this will depend on what equipment and network access you have.
VPN (Virtual Private Network) and direct drive mapping
The Warwick VPN allows your workstation to behave as if it is connected directly to the campus network. This means you can use your normal M: and H: drive mappings. This is the only method we recommend when you need to use database applications, including Microsoft Access files. More details on the VPN are available at https://www.warwick.ac.uk/go/vpn
MyFiles WebDAV folder mapping
Your second option, mapping a drive letter to the WebDAV share is similar to the direct option, but there are subtle differences. It uses the same communication method as a web browser, so is not blocked by the campus firewall. Because of this, you can use this from anywhere, without the need for the VPN. However, some software, for example Microsoft Office, will behave differently. File locks for multiple users accessing the same file will work differently, for example. For this reason we don't suggest you use it on databases or in some multi-user access scenarios. More details about MyFiles WebDAV here
This is the web browser interface at https://myfiles.warwick.ac.uk and is, again, available anywhere. However, you will need to download files to your local system, and then upload them again when you have finished working. Although MyFiles Web can be used anywhere you have a web browser, the offline nature of the file access means it's really best used in lone working situations where your editing a file will not get in the way of anyone else.
