Archiving sizes

Hi, I’m a newbie with em client, so apologies if this is in the manual (I didn’t spot it- just point me in the right direction). 
I’ve been using outlook for many years and I’ve a lot of archived messages, which it would be nice to access in em client.   Is there a limit on how big the archive can get?  I don’t want to import 30odd GB and have it break.


There is no theoretical limit, however, as the database gets larger, performance with be negatively affected.  I don’t think 30 gb is too huge to handle for eM Client.
