run files one by one

Hi,
Anyone know how to run files using batch file.
I want to start 3 pgms IE.exe,utorrent.exe, mailclient.exe
I tried the batch file with the exact path of the file one by one.
But pgms open only after i close the pgms.
eg.
c:\…ie.exe
c:\…outlook.exe
c:\…..ad.exe
saved as bat file.
First ie.exe runs, but then nothing happens.
If i close ie, then outlook runs. After closing outlook, ad.exe runs.
Anyone know how to run pgms one by one auto, I don’t want to use start when widows start, i want it when i needed.
Also any software to do that.
Thanks.
