in reply to Local File vs Uploaded File

Sweet. That looks like it will be helpful in configuring my Apache server.
Can someone please answer my original question about uploading a file vs opening it on the client computer?
is it possible?
Which is more efficient to upload, open, process, delete, or open, process, garbage collect.
fortunately this is not a production server; I am still learning, and relatively new to web page programming. Thanks for the assist.
