How to create a Batch file

Hi friends ,
I want to create a batch file can anyone tell me the steps which I need to follow for creating a batch file.

You need to follow few steps.

1. Open a notepad file.
2. Type
   
   start/d "C:\Program Files\Mozilla Firefox" firefox.exe
   start /d "C:\Program Files\Microsoft Office\Office12" EXCEL.EXE
   
   Note
   
   • There will be different path for Windows Xp and Vista.Window Xp uses MS Office as extension for opening the file (Office 2007 is used in the example).
   • Where start tells Windows to open a separate window to run the specified program.
   • The /d switch tells start command the path of the program. For starting Excel and Firefox, notice that the paths are in quotes, which is needed when there is a space in the file path.
   
   
3. Now it's great that all two programs are open.
   
   • But if you need to open an website in Mozilla firefox For example www.yahoo.com than the commands go as this
   
   
   start/d "C:\Program Files\Mozilla Firefox" firefox.exe www.yahoo.com
   
   
4. This way you can open any number of files/application.
   
   
5. Most important don’t save the file with extension as .txt save it as .batthan only the batch file will be created.
