Had send almost 2gb-rar-data to email-adress.
Since i had to make some corrections which led to repetition of transferring data i accidentally have seen that one can eighter send data by email or link. which i didnt know before.
of course recipients mailbox cannot handle that size!
so obviously second transfer was link-information.
Also strange is option to let data stay online for 7 days when having plus-paid-version.
thought 7 days were default in free-version.
Maybe they thought they could further limit. but i didnt see yet. wierd
