Large transfers received via the drop link have the same availability periods as transfers made in "send mode".
The availability period is the one you choose, via the Settings tab in your account.
Files received are available for 7 days by default, up to 30 days.
At the end of the availability period, just like sent transfers, received transfers and the files they contain are automatically deleted from our servers. They become completely inaccessible and it is not possible to reactivate the transfers.
