How to download directly into Dropbox?

[Rends]

If i try to download let´s say zip or rar files i can open the stuff directly in the ftp client pro app.
The other button "Open in" seems not to work.
But i would like it to save the stuff in the Dropbox .
Can this be done?

Edit: zip files works with the Dropbox. So i guess it is Dropbox related that it can't handle .rar files

GoodReader can upload/download just about any file type with DropBox. You set it up under the Connect to Servers section in the right panel. It will also zip/unzip files. No .rar support though.
