When you click the 'download' button on a jazzorg file (or any other site download), the jazzorg programme notifies your browser that it is ready to download a file.   Your browser takes control and asks you whether you would like to 'open' the file (thus only keeping it in 'memory') or save it to disk.   If you opt for saving to disk, your browser will then either ask you where would you like to save it or stores it straight away in a predetermined folder, usually called 'Downloads'.   The file is transmitted between jazzorg and your computer in 'packets', which are then reassembled in your computer (See the FAQ on download speeds).

Once the download is finished, you can then operate on the file in your usual way, relocating it or opening it to display, print or execute.   The most popular download file types are .pdf, which is basically an image file used for display of text and images and .mp3, which is a 'compressed' file used for faster transfer of audio files.   When a large file or group of files need to be compressed for convenience or to minimise the download time, a widely-used compression technology is applied to create a .zip file (See the FAQ on Zip files).   Some download files have a .exe subscript, which signifies an executable file and your browser will normally warn you that they could hide something nasty - it is important, therefore, to be able to trust the source of your .exe download.   There is no voodoo in downloads, your computer and the website are sending and receiving data packets all the time you are working on-line, just to sustain your interaction with the site.
