How can I upload a folder with a files? without select a each file, and without use FTP only with HTTP
with http: not at all. As coppermine admin, you should perform FTP-uploads plus batch-add as suggested in the docs that come with coppermine.
Is it not possible to integrate some kind of java app to be able to do this?
Perhaps integrating something like this: http://www.javazoom.net/applets/jclientupload/jclientupload.html
there have been mods posted that do a similar thing for coppermine. However: you can't beat FTP uploads, performance-wise.
Thanks is great that app
