Sure, if you are more familiar, you can run editors in the terminal such as
Choose File > Download Project to download
ide50.zip, an archived file (in
.zip format) of your workspace files.
If you backed up your work per What’s the best way to back up my work?, and you would like to restore it in a different (or same) workspace, upload

.c9folder appearing right under my
~/workspacefolder, that I haven’t created. Is this normal?
Yes, this is totally normal. If curious,
~/workspace/.c9/ is used by Cloud9 IDE (and CS50 IDE) to hold some workspace settings, your undo history, and other metadata.
Generally, you shouldn’t touch this folder or its contents. Files and folders whose names start with a dot (aka dot files) should be hidden by default. You may want to hide the
.c9 folder (along with any other dot files) by clicking the gear icon atop the file browser on the left and unchecking Show Hidden Files.
Old workspaces used to have less than 5GB of total disk space. This may be problematic particularly when running

Go to https://github.com/check50/<your-username>/invitations and https://github.com/submit50/<your-username>/invitations, after replacing
<your-username> with your actual GitHub username, and click Accept invitation, then try

If curious why this happens, earlier the Authorize Application step was sufficient for adding your GitHub user as a collaborator with write access on your check50 and submit50 repositories that we automatically create for you, but GitHub updated their API recently to require users to accept invitations for repositories they’re added to, so the Authorize Application step isn’t sufficient any more, and you have to accept these invitations.
