Introduction to Ascp 4

Ascp 4 is a FASP transfer binary that is optimized for sending extremely large sets of individual files. The executable, ascp4, is similar to ascp and shares many of the same options and capabilities, in addition to data streaming capabilities.

Both Ascp 4 and Ascp are automatically installed with IBM Aspera High-Speed Transfer Server, IBM Aspera High-Speed Transfer Endpoint, and IBM Aspera Desktop Client.

As installed, Ascp is used for transfers started from the GUI and Ascp 4 transfers can only be initiated from the command line. For information on how to make GUI-initiated transfers use Ascp 4, see Using Ascp 4 from the GUI.
