.psdc file

We have a studet in our school. She createdAdobe cloud data. After the left the school, here Adobe account was deactivated. I saw here account but not as an active one. I shared here data with my Adobe account and was able to download a .zip file. This file contains a couple of .psdc file, but these files can’t be used in Photoshop for example. We want to help the studet to either:

• Convert the Adopbe Cloud files (.psdc) or
• Activate here Adobe student account, that she is able to work with the cloud data by here own.
