问题
is there a way to influence the browsers download directory for a given HTTP download? The scenario is that some of our users are complaining that they have to click through the directory structure whenever they download a file. As I don't know their individual preferences, it would be nice to make the browser use the last chosen download directory. Is this possible? I know that users can choose their download destination from within most browsers' options dialog (firefox, chrome, etc.), but can I influence that behavior from the server side?
Thanks, Mo

Server side, no. Your browser client controls where to download in the Preferences/Options (depending what browser you are using).
However, you can via JavaScript. Take a look at this control:
- ($$) http://www.ardentedge.com/pr_fd.htm
or if you are only using IE, you can use this:
document.execCommand("saveas",false,"c:\\where\\yo u\\want\\to\\save\\it\\to.txt");

You can use Content-Disposition to set the filename, as far as I'm aware you can't set the folder as this would be (at least) platform dependent:
header('Content-Disposition: attachment; filename="downloaded.pdf"');

It might be possible using a Flash movie, but without resorting to client plugins (using normal HTTP/HTML) this is not possible (mostly for security reasons).
Users can control this in most browsers using their settings.

'Classic' web content can't access the local file system. Maybe there is some voodo magic hidden inside ActiveX components or Java applets that would be able to do such a thing, but that could potentially be very complex / restrictive / dangerous.
If there is a routine in which user needs to download which file, you could consider writing a simple HTTP client application that handles the whole process for the user.
