Thin Upload is a general purpose multiple file uploader.
EditBy: Thin Upload is a general purpose multiple File Uploader. Once Thin Upload is installed on your website, visitors will be able to send you their files simply by dropping them the designated area of their browser.

With traditional HTML form based uploads, each transfer is limited to a handlfull of files. With Thin Upload thousands of files and folders can be sent at once. A browse button can also be displayed for users who may prefer it, this button can also be used to select multiple files and folders.

Another difference Between HTML forms and our applet is that the maximum upload size can be checked before a single byte has been transfered saving bandwidth. Another feature of the applet is its ability to display a Progress monitor while the files are in transit.
As easy as drag and drop
