Choose your sharing route
Official limits and instructions checked . Personal free allowances depend on current usage; work/school policies and menus differ. No paid plan or trial is required for these bounded routes. Stop or choose another existing route if capacity or restricted access is unavailable.
“One-time” means one task followed by your manual cleanup, not a single-use link. Viewing may allow downloading or copying. Revoking a link cannot recall copies already received. This guide makes no end-to-end encryption promise; cloud providers store the files you choose to put there.
