Express Transfer overview

Express Transfer is an installed desktop application that is specially designed to support large structured and unstructured data file imports greater than 20 GB. This desktop solution will help reduce the time and effort it takes to move your data into RelativityOne. See Installing Express Transfer desktop application for the installation steps.

Note: You must have Import/Export installed before being able to use Express Transfer. See Installing Import/Export.

When you use Express Transfer, you do not need to zip the data files before importing them. You simply choose the data file from the local source folder and run the import process. This feature is available for Microsoft Windows and Apple MacOS users.

To ensure that you always have the most recent version of Express Transfer, it is configured to automatically update with each new version. However, you can change this setting if desired. See Automatically updating Express Transfer software for more information.

Refer to the Import/Export in RelativityOne video for additional information on how Import/Export and Express Transfer work.
