Smb4K

Free plan Linux

What Smb4K is

Smb4K is free software for finding network neighborhoods and mounting Samba shares on Linux and BSD-family systems. It scans workgroups, hosts, and shares through Samba’s client library and DNS Service Discovery, with optional WS-Discovery. Users can preview shares, bookmark favorites, define server and share settings, and create profiles for different network arrangements. Shares can be mounted or unmounted, then opened through a file manager or terminal. Linux supports CIFS and SMB3, while BSD systems use SMBFS. Smb4K can synchronize a remote share with a local copy in either direction. Login credentials can be stored through secure QtKeychain options. The project lists Linux, FreeBSD and derivatives, and NetBSD as officially supported; DragonFly BSD is also listed among supported platforms. Source and distribution packages are available, with forums and a bug tracker for support. It is licensed under GPL v2+.

Who it suits

It suits Linux and BSD users who need a graphical network-share browser, mounting utility, and synchronization features. Administrators can also use saved profiles and credential storage for different network setups.

Free GPL v2+ software
Discovers workgroups, hosts, and shares
Mounts and unmounts network shares
Supports share synchronization in both directions
Secure credential storage options

What to know first

Verdict

Smb4K provides network discovery, Samba-share mounting, previews, bookmarks, and synchronization without a purchase cost. Its supported systems and post-security-fix mount-prefix restriction should be checked before deployment.
