Students are not currently required to encrypt their USB devices. However, an encryption message will appear if a student uses a USB device in a university PC that is logged in to by a member of staff (for example during a tutorial).
There are two options:
1. If the student just needs to be able to open a file: insert the USB device and choose 'don't encrypt' when the message appears
2. If the student needs to be able to save to the USB device: go to 'start menu' > click the arrow next to 'shut down' > choose 'switch user'. The student will then be able to log in and insert their USB device to use it as normal. The member of staff doesn't need to log out and can subsequently switch back to their log in.
Please note that encrypting a device will have implications on where and how you can use it.
