How to run an .exe file from AX?

Hi Friends,

Can anyone tell, how I can run an .exe file in a specified folder from AX? On running that .exe file, it sends a text file (input.txt) and receives another text file (output.txt) from an website.

Also, how I can import few specified columns from the output.txt file to the AX table?

Note: Text files are with fixed field length.

Thanks,

Aarvi
