The short answer is no you can't import a .ccf file. The file type for use with the iPronto is a .icf. You will have to build the visual look of the file from scratch or modify the factory one. You can use the library of IR codes that exists on remote central by using the cut and paste feature.

Frankly due to the screen size and the color capability of the iPronto it wouldn't make much sense to utilize an existing ccf file anyway.
