JUpload - File Upload Applet

Since Java 1.7u51, to use the applet, you'll need to install our root certificate. Before the applet was auto-signed.
But now, you'll have to install this certificate (updated on 26 January 2014) as a certificate authority. Your browser will install it.
For details, please read these explanation: this page.

The applet : independent tree view mode
In this mode, the added files and folders are added 'as is' to the upload root hierarchy. That is: if you drag'n drop a folder, it is attached on the root of the upload, with all its children, grand-children (...) attached to it. This structure will be uploaded to the server, which can then reproduce it. It can be useful to reproduce a local substructure of the file system, on server side.

Java 1.5 or higher plugin required.
