When you share a folder, you assign a role to the people you invite to the folder. Depending on the role you assigned, that person may not be able to download files, edit files, or do other actions. You can change the role assigned to someone as needed
If you email a Member link to someone, that person must be able to log in to Oracle Content and Experience to access the files in a folder. If you need to share a folder with someone who doesn't have access to the service, email a public link instead.
If you created a public link for a folder then emailed that link to someone, that person may not have the necessary rights to the folder. The default role for public links is Viewer but you can change the default role. To see the defaults for your account, click your user name and then click Preferences.
