Sidecar Properties

Cornerstone stores additional information about a file property’s contents in a sidecar property. This information includes: the original file name, file type, UTI, size, Unix permissions, thumbnail image, dimensions (if applicable) etc.

The name of the sidecar property is the same name as the file property itself with an “:attributes” suffix. For example, the sidecar property for a thumbnail property would be named thumbnail:attributes.

You can prevent Cornerstone from creating sidecar properties by unchecking the Save information about file contents in sidecar properties option in the User Properties preference pane.

Packages

Package-format documents (i.e. files that are actually stored on disk as folders) are compressed in .zip format before being stored as a property.
