'How do I break existing links between InCopy and InDesign? I have picked up a file from a previous design group that requires me to check in and check out every time I open and try to edit the content.'
Incopy/indesign
If you are sure that you want to sever the link between InCopy and InDesign, and do all further editing of all stories in InDesign, you can just go to the Links panel, and select any .icml, .icma, or .incx files you find there (the file types vary depending on your version of InDesign/InCopy). Then just choose Unlink from the Links panel menu.
