You may need to collaborate with other people and share information, but you want to make sure only the right people have access to that information. The type of sharing you use depends on what you need to share:
Files: You can create a link and email the link to someone or use it in an instant message or a document or another app. Sending a link is useful if you need to give access to people on an as-needed basis to specific files. The only way the recipient can access the file is by using the link.
Folders: you can send a link to a folder or you can add people or groups as members to the folder. When you add members to a folder, those people and groups can access all the content in the folder. This is useful when you're working on a large project, for example, and people may need to continually access information.
Viewer: Viewers can look at files and folders, but can't change things.
Downloader: Downloaders can also download files and save them to their own computer.
Contributor: Contributors can also modify files, update files, upload new files, and delete files.
Manager: Managers have all the privileges of the other roles and can add or remove other people as members.
There's also an Owner role with all the permissions to manage a folder, including deleting the folder.
Contributors and Managers can delete content and delete subfolders. If a shared item is deleted, it appears in the Trash folder of the person who owns the item and the person who deleted it.
When collaborating with partners and outside vendors, you can provide secure public links to files so everyone has the right level of access. You can also set access codes and expiration dates on links to add more security. You can also maintain oversight by monitoring who accessed which shared files and when.
