hello who to change the blockchain datadir directory ?

>>The default path is Drive :\Users\Username\AppData\Roaming\Sia-UI\sia\consensus. if you changed it im not sure SIa will know where to locate it unless theres  a config file you can use set the path to the db.

other question if i cannot open port on my nat is this a problem if i wanna share hard disk space?
>> "Shift-Cntl-L" under  "hosts" will let you know if your host is reachable . You can manually add an NAT entry to your router.
The SAI app also prints "Host unreachable" in red  on the top of the app if  your host cant be reached.


1 more question  is it possible to share a file for 1 day?  or will we pay automatically for 1 month ?
