FileDownload, downloading data from Server to Client/Share

Question

Hello together,
my Web Dynpro Application shall save 4 Files to the client or to a share.
If the User presses SAVE DATA on the application, the data should be saved in a table (this is already done) but also the new and the old data should be saved in 4 Files on the client or share, without pressing any other Buttons or something else.
This new and old data are divided in 4 Files. I already did the file Download with a Button, and on the browser there comes a popup and i can save this files - > but this is not what it should.
Can somebody please HELP?
Regards Chris

Remember you are in a web browser, not a desktop application.  There is a security sandbox that protects the client machine from web browser access.  The only way you are going to get slient downloads of multiple files in Web Dynpro is with the AcfUpDownload UI element in 7.01 and higher. It uses a signed Java Applet to get around the browser security sandbox.
You sya you need to write this to the clietn or to a share.  Is the file share accessible from the file system of the ABAP application server?  If so you might have a much easier time writing the files to the file share via normal ABAP Dataset commands. This won't involve the browser at all since the ABAP application server will write directly to the file share.
