Synopsis: Suggestion for handling spaces in filenames State-Changed-From-To: open-closed State-Changed-By: marc State-Changed-When: Sun Dec 7 21:32:24 PST 1997 State-Changed-Why: Apache does not tell the client what filename to use and has no control over it. If the client you are using is saving things in that manner and you don't like it, you really need to take the issue to the client vendor.
URLs can not have spaces in, period. What the server chooses to call the file once it downloads it is up to it. Some clients to behave as you want and put the spaces in.
