It seems like it's a little stronger constraint than "partially user selected". The users need enough knowledge of one part of the filename plus the ability to influence the other part to force the hash.
Sure? If several last parts of the filename have the same length and CRC and are combined with the same first part of the filename (even if this first part is unknown), why would the resulting CRC not clash?
We are not talking about cryptographic hashes here.
