Oh it absolutely is. Bringing files into Be is fine. The file type sniffer runs in the background and adds whatever metadata it can in a lightweight quick way. IIRC there are addons for specific file types like media files that add nice things like author, runtime, etc.

Sending them out is a pain though. All the metadata is usually lost and from what I recall even emailing a file from one Be machine to another could be difficult. IIRC you could zip them and the metadata would make it, but raw files and tgz would lose it.
