title: Read data from Informix Database. Having folder app.dbs with *.IDX, *.Dat files
body: <p>I have a friend who has a management application, and he would like to import some of his data in Excel.</p>
  
  <p>The thing is I have no idea about how to read this type of files,</p>
  
  <p>In his application directory he has a folder named app.dbs. Inside there are *.idx and *.dat files.</p>
  
  <p>What would be the easiest way to read this files? Maybe ODBC connector, or installing some version of Informix DB?? </p>
