What a share link recipient sees

Anyone with a share link can use it without an account.

A single-file link opens a page with the file name and size, when the link expires (or that it never does), how many downloads are left if a cap was set, and a Download File button. If the link has a password, a Password Required page asks for it first.

A Quick Share link opens a page listing every file in the bundle with the sender's message, plus Download All (.zip) and a Download button per file. Each recipient's link is unique to them and should not be forwarded. A password may be required here too.

A dead link shows This link is no longer active and says why: expired, download limit reached, or revoked.

A signing link is covered in Signing documents.
