I am currently doing research on a new abstraction for files. For usecases, I am looking for applications that create/manage a lot of files (perhaps temporary files). I know that some mail servers store each email as a separate file. Going by a previous post (https://news.ycombinator.com/item?id=12209028), Angular development involves a lot of files being created. Compilers seem like another application that create temporary files.<p>Are there other such applications/scenarios that I am missing?
