    Windows Share SMB 2/3 V1 Connector Configuration Reference

    Table of Contents

    The Windows Share connector can access content in a Windows Share or Server Message Block (SMB 2 and 3 protocols)/Common Internet File System (CIFS) filesystem. Available in Fusion 5.x.x releases.

    V1 deprecation and removal notice

    Starting in Fusion 5.12.0, all V1 connectors are deprecated. This means they are no longer being actively developed and will be removed in Fusion 5.13.0.

    The replacement for this connector is the Windows Share SMB2/3 V2 connector.

    If you are using this connector, you must migrate to the replacement connector or a supported alternative before upgrading to Fusion 5.13.0. We recommend migrating to the replacement connector as soon as possible to avoid any disruption to your workflows.


    When entering configuration values in the UI, use unescaped characters, such as \t for the tab character. When entering configuration values in the API, use escaped characters, such as \\t for the tab character.
