manugraph Well, yeah, I'm not a user of any commercial cloud protocols anymore for years now, but I did consider it a unique selling point of MiX in the past (because it allowed to keep away from the proprietary apps). But apart from the obvious WebDAV, I do still use SMB, FTP and MiXplorer's FTP(S,ES)/Share Server and sometimes its HTTP/WebDAV Server.
Apart from that, it's got great view modes, (file type) filtering and detailed recursive search, a decent RegEx (multi-)renamer, great operation queue management, quick shell command execution and overall exhaustive customizability. Material Files isn't there (yet), but I'm sure that if you use it for a while, you eventually won't miss the stuff you've gotten used to in MiX anymore.
