How to Compare Two Document Versions Side by Side in zipBoard
To compare two versions side by side, use zipBoard's powerful version comparison feature to track changes easily. You can launch this feature using two different methods: open the asset in the Asset Viewer, click the Version Dropdown, and select Compare Versions; or switch directly from the Markup View to Compare View using the Exit Compare button without leaving the page. Once in Compare View, simply select your older version for the left pane and the newer one for the right pane.
To use the version comparison feature, your asset must have at least two uploaded versions. If an asset only has a single version uploaded, the comparison option will not be available or active, as there is nothing else to compare it against. Make sure you have uploaded a newer revision or update of your file before attempting to start a comparison.
