Sharing¶
Shared files or directories are counted against the owner’s quota and not the “shared-to” user’s quota.
Resharing¶
If user A shares a file with user B who then reshares a file to user C, the space occupied by that file is counted against user A’s quota.
Public sharing with upload permission¶
If user A publicly shares a directory via a link and enables “public upload” permission, files uploaded to that directory from the outside are counted against user A’s quota.
