Introduction to Ascp4

Aspera Ascp4 is an optimized transfer engine based on FASP technology. Ascp4 is designed for sending extremely large sets of individual files efficiently. The executable, ascp4, is similar to ascp and shares many of the same options and capabilities, in addition to data streaming capabilities.

Both ascp4 and ascp are automatically installed with IBM Aspera High-Speed Transfer Server, High-Speed Transfer Endpoint, and Desktop Client applications.

As installed, ascp is used for transfers intiated from the GUI and ascp4 transfers can only be initiated from the command line. For information on how to make GUI-initiated transfers use ascp4, see Using Ascp4 from the GUI.
