Using remix.ethereum.org, here is an example that can help.
The input, which is the same as calldata, is 0x29ae811475944220b52381f169021a7c3f2947dfd0d2b1fb95e6cd92358e0a7997c8a9a1000000000000000000000000000000000000000000000000000000000000000f. (This is calling file( 0x75944220b52381f169021a7c3f2947dfd0d2b1fb95e6cd92358e0a7997c8a9a1, 15))
I will update this answer and wanted to give you something to work with sooner.
