How to Get (Retrieve) a File

This section describes how to get (retrieve) a file. This procedure applies to all CFDP modes.

Special Note: ISS Change Request (CR) 13351 Ku-Band Forward Access for Payload Operations only required support for the “Put” directive. Therefore, the Get directive is not supported in all ISS CFDP implementations. It is supported by TReK when both the sender and receiver are TReK CFDP implementations (TReK CFDP application, TReK CFDP console application, or TReK CFDP Library).

1.

The CFDP application must be configured and the CFDP service must be active.

2.

Enter information into the “CFDP Commands” area for the file you wish to get. Ensure the Get, Transmission, Source, Remote EID, and Destination information is correct. The Source field should identify the absolute path of the file to be retrieved from the target entity. The Remote EID should identify the target Entity. The Destination field should identify the location (including filename) where you want the file to be stored when retrieved.

3.

Push the Execute All button.

Note: When entering Source and Destination information in the CFDP Commands List, do not wrap the Source and Destination information in double quotes as you do on a CFDP Command Line.

Note 2: If you want to transfer the contents of a directory, you can enter the absolute path for a directory in the Source and Destination fields. All the files in the first level of the directory will be transferred. Subdirectories will not be transferred. Be sure to include a forward slash ‘/’ at the end of the directory path.

If the text is red, this indicates there is problem with the information provided. Until this is corrected it will not be possible to successfully perform the file transfer.
