While the Video Uploader application was available as three separate downloads, the Linux version was written in Java, a cross-platform programming language, and would therefore also work on other operating systems without modifications, providing that the Java Runtime Environment (JRE) is installed. This Java executable (.jar) file was a standalone application that did not require installation. Consequently, it could be run from removable media such as USB flash drives, CD-ROMs, or network storage. This allowed users to upload video even if the computer terminal on which they were working would not allow them to install programs, such as a public library computer.
