executting a file from blender?

Is it possible to execute an .exe within a blender script? I want to use an external converter for a file exported from blender but Im not sure if its possible.

You could use the system or spawn (spawnv, spawnl, …) functions from the os module.

Edit:
Ok Ive found it! thanks for the tip it was the OS module but the correct command is popen() this works in blender!


import os
a=os.popen("dir").read()
print a 

This will execute dir and pump the results on the output window.

Is this OSI?
