Click 'Browse Materials in Cosmos'.
The Chaos Cosmos Browser window will open (if you get an error, see the Troubleshooting section at the bottom of this page).
In order to download materials, you have to sign in. Click 'Sign in'. Create a free account if you don't have one.
After signing in, the Sign in link will change to a profile badge.
Before downloading materials, change the download location; otherwise you will get the error "No access to downloads folder".
To change the location, click the three dots and choose Settings.
Click Change and choose a new location. We suggest using a folder within your 'OneDrive - Syracuse University' location.
Warning NOTE: If you get an error when trying to change the download folder location, it's usually because you had previously clicked 'Download All'. You have to wait for it to finish going through that process (it will fail each time it tries to download a material). Sad but true. Then when it's done, you should be able to change the location. Now you should be able to download materials and import them into your project.
