An SMB (Server Message Block) Share is a network file sharing protocol that enables applications to read, write, and request file and print services on remote computers or servers over a local area network (LAN) or the internet. SMB is commonly used for sharing files, printers, and other resources among multiple users or devices within a network.
SMB Share allows users to access files and folders on remote servers as if they were on their local machines, enabling collaboration, data sharing, and centralized file storage. The protocol supports various operating systems, including Windows, macOS, and Linux, which makes it versatile and widely used in various network environments.
SMB has evolved over time, and different versions of the protocol have been developed. The latest version, SMB 3.x, comes with enhanced security, performance, and reliability features compared to earlier versions.
In summary, an SMB Share is a way to share files and resources across a network using the Server Message Block protocol, facilitating collaboration and centralized data storage in multi-user environments.
SMB Shares can handle large files, but the actual file size limit depends on the version of the SMB protocol being used and the file system of the shared storage.
For SMB 2.x and SMB 3.x, the maximum file size limit is 16 exabytes (EB) minus 64 kilobytes (KB). However, this theoretical limit is usually not reached in practice because the underlying file system itself imposes its own file size limits. For example:
NTFS (New Technology File System) – used in modern Windows systems – supports a maximum file size of 16 terabytes (TB) minus 64 KB.
HFS+ (Hierarchical File System Plus) – used in macOS – supports a maximum file size of 8 exabytes (EB) minus 1 byte.
ext4 (Fourth Extended Filesystem) – commonly used in Linux – supports a maximum file size of 16 terabytes (TB) to 1 exabyte (EB), depending on the specific configuration.
In general, SMB Shares are capable of handling very large files, with the actual limit typically determined by the file system on the shared storage rather than the SMB protocol itself.
