Advanced JavaScript with Internet Explorer: Working with Drives and More

This series mainly concentrates on retrieving system information using JavaScript and displaying the same on a web page. All of the examples in this series can be directly tested by copying and pasting the entire code (of each section) in any text file with the extension .HTM and opening it using Microsoft Internet Explorer (preferably 5.5+).

The above code is very similar to the code provided in the previous section. The only difference is that I am displaying the details of each drive (drive name and size) in a table (rather than simply using a <BR> tag).
