I actually use SeaFile for some clients (since OwnCloud doesn&#x27;t do client side encryption at all), after Wuala shut down last year. I actually was disappointed by the security and features too (<a href="https:&#x2F;&#x2F;forum.seafile-server.org&#x2F;t&#x2F;encryption-the-pro-added-features&#x2F;3887" rel="nofollow">https:&#x2F;&#x2F;forum.seafile-server.org&#x2F;t&#x2F;encryption-the-pro-added-...</a>), you cannot securely share sub trees&#x2F;dirs like in Wuala (with their Cryptree).<p>Is there a better FOS alternative?<p>The Wuala service did had a lot&#x27;s of deadlocks, either on server or the client side, and customer service was not done secure: please send over the log files (included file names) or the client storage block, etc...
