CDBurnerXP

  Today I've decided to feature a burning software that is a free alternative to nero.Mind you I'm not saying this has the all the features of Nero;its just that this one is a light and simpler alternative.
  My idea here is to give a short tour of cdburnerxp so that anyone can use it.Starting off here's the startup screen:

The different options are listed out as in nero..
  The next page is used to add data to the disc:

 

The data should be added to the corner indicated on the screen.
  The next option is multisessioning;to enable this select leave disc option.The advanced settings options allows one to set writing speeds,verify data after burning and so on..

In case a new disc is inserted you can continue multisession(select continue disc);else starting a new session will delete older data:

However creating multiple sessions on a cd/dvd can cause issues when you try to read data after writing.This I learnt from personal experience.

  I hope this turns out to be useful..
