Holly is having issues saving files onto her hard drive and she's concerned that she may be running out of storage. Leo says that it's probably not the hard drive that's causing that — it's probably her cloud storage on Google Drive. She has a limited amount of storage online and if she's exceeding that, then she's going to have those problems.
Leo suspects there's an app that is syncing with Google Drive. There's probably a folder on her hard drive that shows that. She should look on Google Drive and see what's there. Chances are, that's what's happening. Google is backing up and syncing to Google Drive and she's running up against a limit.
