Report and dashboard folder sharing
Key Takeaway
You share the folder, not the report or dashboard, and what a user can do depends on both their folder access level and their user permissions.
Reports and dashboards are organized in folders. Sharing a folder gives people a View, Edit, or Manage access level on it, and that level works together with the report and dashboard user permissions they hold.
Folder access and user permissions work together
Opening a report or dashboard takes two things: access to its folder and the needed user permission. For example, running a report needs access to its folder and the "Run Reports" user permission.
Folder access alone does not decide what you can do with a folder's contents, because user permissions also count.
For example, imagine a user with Manage access to a folder who holds only the Run Reports permission. That user can run a report in the folder, but cannot edit or delete it.
