What is an INCP file?
Package used by InCopy, a professional writing and editing program that tightly integrates with the Adobe InDesign page layout program; contains an .INCA file and its associated .INCX files; used to package a subset of an InDesign document for remote editing.
INCP files are exported by a designer with InDesign, modified by an editor using InCopy, and then sent back to the designer as an .INDP package. The INDP file can be imported back into the original InDesign document (.INDD file) using InDesign.
NOTE: As of InDesign and InCopy CS4, InCopy package files use the .ICAP extension.
