WordPress.org

This plugin allows you to upload single files or entire directories with subdirectories to your Dropbox account. You can use it for backup, synchronization or whatever uploading tasks you may have.

Features overview:

• Upload entire directories with subdirectories to your Dropbox account.
• Backup your entire site files by pointing to the WordPress installation directory.
• Specify a Dropbox folder to which your files should be uploaded. If such folder doesn't exist it will be created.
