I simply wanted to know if it had been set to that as Bitcoin Core often suggests you do this during install if you don't have a lot of storage space and Armory doesn't work with Bitcoin Core in pruned mode.
Oh no, during the install i have set Bitcoin Core prune, in fact the blockchain is just 5 gb, but the download took 24 hours!
So i have to reinstall the entire Bitcoin Core? Or just use the reindex mode with Bitcoin Core for gets the correct blockchain requires by Armory?
