I'm designing a website that will let the user synchronize a local folder to an online folder (Kinda like dropbox).
I'm trying to find a way to avoid developing a local tool to do the download and synchronization. And do it somehow online.
Is it possible to download multiple files in a certain directory tree? Can a website have free write access to local directories?
A zip file is not an option, since the file batch could get pretty big.
EDIT: Synchronization shouldn't occur periodically. Just when the user logs in the website.
