In Gridfs many large companies name their buckets/colllections according to their business model.

such as:
customer1.files
customer1.chunks

customer2.files
customer2.chunks

Since the -c or collection option is missing from mongofiles it can't be
used to put files into collections that are not named fs.chunks/fs.files

Since you can't create custom collection and bucket names with all the other tools we would please like mongofiles.exe enhanced so it can support a customized data model.
