## FAQ

### Is Seafile faster than Nextcloud?

Seafile is widely regarded as faster for syncing large numbers of files because of its block-based storage and delta sync. Nextcloud trades some sync efficiency for a much wider feature set.

### Can I browse Seafile files directly on the server disk?

Not directly. Seafile stores data in its own block format, so you access files through its clients, web UI, WebDAV or the FUSE extension rather than the raw folder.

### Does Seafile have calendars and contacts?

No. Seafile focuses on files. If you need calendar and contacts sync, Nextcloud includes them.
