download capabilities along with related file manipulation routines.
It lets you to create robust and powerful file upload system that can be available
right from your web browser. Intuitive user-friendly interface,
ability to transfer files of unlimited size and customizable options make Vault Applet

The applet has upload progress bar indicator allowing you to see the progress of your file upload
in real time. Warning/error message system gives the possibility to inform
user about any collisions occurred during the upload process.
User can add/remove files to the batch list, rename
files and folders, cancel running process.
Files for upload can be selected from both local and network-mapped folders,
optionally including all sub-folders. Additionally, user can enter any
valid network path and browse it in the file selection dialog.
Large File Upload/Download
The most powerful feature of Vault applet is the possibility to upload
large files (unlimited file size) with no timeouts or memory lacks (known
java bug).
Our file upload/download applet provides fast and high-performance
file transfer that works over http, SSL (https) with or without proxy. This
is achieved by using browser's native connection classes.
Vault uses all available network traffic,
so the file transfer will go as fast as your LAN/WAN allows.
You can submit your form data together with the file. It is usually
required to send some application state information back to the server.
Extended Functionality
You will probably wonder, what else can you do with Vault applet that you are unable to do
with a usual FILE form input field? Well, you can control, filter and preprocess the
file list that user has selected. You can enable or disable transferring of
some file types based upon your application logic and collect
additional information related to those files. And finally, you don't
need to reload your page while you transferring the files.
We use the standard "multipart/form-data" content encoding, so the
applet is compatible with any server-side uploading component. The
quality of the server-side component as well as the hard-drive
performance will also affect the resulting transfer rate.
