When sharing EIP files, catalog users can benefit from EIP export for simplified transportation of RAW and settings files and profiles. In the Export originals panel (File -> Export Images -> Originals -> Options), you will find an option Export as EIP. Sessions users can also choose Export originals as EIP files. In both cases, this creates a workflow where the original RAW file and adjustments are copied and exported as a single EIP file.
Although EIP files can be imported into a Catalog, with or without any previous adjustments applied like in a Session, EIP files cannot be unpacked in a Catalog. It is therefore recommended that EIP files are unpacked before using them in a Catalog or that they continue to be handled in a Session.
