.ICAP File Extension

Package file used by InCopy, a writing and editing program used with Adobe InDesign; stores an .ICMA file and associated .ICML files in a compressed archive; used to package subsections of InDesign documents for remote editing.

ICAP files are exported by InDesign, edited with InCopy, and then saved as an .IDAP file, which can be imported back into the original .INDD document using InDesign.

NOTE: ICAP files are used by InCopy and InDesign CS4 and later. Previous versions used the .INCP extension.
