    Hi all,
    I'm working on a system that involves clients that reproduce certain files,
    and a server that processes them. I have a dilemma regarding the way the
    files should be passed to the server. The problem is that the files might be
    as large as a few tens of MB, and there might be a few tens of files.
    Therefore, the fastest way to create them is on the clients' machines.
    However, the server expects to see them on its local disks as well, to avoid
    extra networking while they are processed.
    When dealing with files, nothing makes more sense then using the file system
    interface (explorer, dos commands, windows API) for moving them from one
    computer to another. This, however, requires some sort of folder sharing and
    having the proper rights. We install our system at various clients, each
    having a different network, and I can't tell how happy would the system
    administrator be with sharing folders. Also, I'd like to have the file move
    automated, since I can't be sure the clients would remember to do that every
    time.
    Another solution is to steam the files over the network. I use DCOM to
    communicate between the clients and the server. I assume passing 100MB files
    using the file system would be done more efficiently then streaming them and
    passing them as strings using DCOM calls (what are the limits for that?), but
    I'd like to hear your opinion about that. What I like about this solution is
    that it takes the users and the network configurations out of the game, but I
    really don't know if that's reasonable or not.
    If you have any other idea as to how to move files from the clients to the
    server while depending as little as possible on the users and the network
    configuration, I'd love to hear it.
    All users use windows, the network could be either netware or windows.
    Thanks,
    Kal
