Introduction to ascp4

Ascp4 is a FASP transfer binary that is optimized for sending 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 ascp4 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 that started from the GUI, and Ascp4 transfers can be only initiated from the command line.
