You could store files of this type in a data warehouse, but given that these things cannot be added up there is little point in treating them as transactions. Instead we can consider them to be master data of a sort. Hence it is reasonable to want to manage them from a master data repository, though this may or may not be relevant to a data warehouse application.
I am grateful to Chris Angus for pointing out that there is a problem with the terms 'structured data' and 'unstructured data'. Historically the terms came into being to differentiate between data that could at that time be stuffed in a database and data that could not. That distinction is nothing like as important now and the semantics have shifted. The distinction is now more between data constrained by some form of fixed schema and whose structure is dictated by a computer application v data/documents not constrained in the same way. An interesting example of "unstructured data" that is a subject in its own right and needs managing is a health and safety notice. This is certainly not just a set of numbers, but it does have structure, and may well be related to other structured data e.g. HSE statistics. Hence this type of data may well need to be managed in master data management application. Another example is the technical data sheets than go with some products, such as lubricants; again, these have structure and are clearly related to a traditional type of master data, in this case "product", which will have transactions associated with it. Yet another would be a pharmaceutical regulatory document. Hence "structure" is more of a continuum than a "yes/no" state.
So, while the lines are blurring the place to reconcile these two worlds may not be in the data warehouse, but in the master data repository. Just as in the case of other master data, for practical purposes you may want to store the data itself elsewhere and maintain links to it e.g. a DMBS might not be an efficient place to store a video clip, but you would want to keep track of it from within your master data repository.
