Download ProntoEdit 4.0.2 from the Classic Pronto Files section and you can open the CCF file. If you download ProntoEditProNG (PPENG) from the Next Generation Pronto Files area (for TSU3000/7000), you can open PCF files and also 'Import' CCF files.
This will allow you to see the Pronto Hex for the codes in question. I strongly recommend using ProntoEdit 4 on CCF files as the PPENG editor may shorten NEC-based codes to a form that may not easily be usable by Crestron.
