CS6 can't delete pages

Hi hanst,

To delete pages you may simply delete them from pages panel or by simply moving first 20 pages to new document. It will not effect text on remaining pages until the text is threaded.

For Details Click here : Manage pages and spreads in InDesign

If the text is threaded then you have to break the thread first and then delete or move pages, for details click here: Thread text among frames in Adobe InDesign .
