Answer 1

Ok, thats fine...my little problem now is that i have the following code:
var BookContents = app.activeBook.bookContents;
for (var x = 0; x <= BookContents.count(); x++) {
     var file = new File("/Volumes"+BookContents[x].filePath);
     alert(file.exists); << This returns true
     var doc = app.open(file, false);
     alert(app.activeDocument()); << This returns null !!!!
     alert(app.documents[0]); << Also returns null !!!!
As u can see i want to iterate over bookcontents, open every doc an change some links.
Now i cant get the doc because this is null....
Maybe you have an idea?
