Here's how to do it with scripting (my preferred method)...

 
function ExpandIDML(fromIDMLFile){//Expands an IDML file into folder format 
  if(! fromIDMLFile){return null} 
  var fullName = fromIDMLFile.fullName; 
  fullName = fullName.replace(/\.idml/,""); 
  var toFolder = new Folder( fullName ); 
  app.unpackageUCF( fromIDMLFile, toFolder ); 
  return toFolder; 
  } 

 

 
function CreateIDML(fromFolder){//Produces an IDML package from the contents of a directory: 
  if(!fromFolder){return null} 
  var fullName = fromFolder.fullName; 
  var toIDMLFile = new File( fullName+".idml" ); 
  app.packageUCF( fromFolder, toIDMLFile ); 
  return toIDMLFile; 
  }
