running .bat after XP installation

[dari0h]

I created a .bat file that should do some customization work after XP installment. It deletes some folders and files from start menu and desktop, adds some others, the little things. So I want to know what would be the easyest way to run that file after installation. I used to add some commands to "rune once" sections but as the number of commands increased I thought it would be better to put all that in one .bat and than put only one "rune once" command that would start the .bat. So where, on cd, should I put the .bat file and with witch command do I access it? Or is there an easyer way?
