Snapshot files list the contents of an image. You typically use snapshot files for packaging image components (ICs) or for just keeping a record of what applications, classes, and methods are in an image at a particular time.

Snapshots created with a Version 4.01 or 4.02 image are not compatible with the Version 6.0 packager. Thus, you cannot package with prerequisite ICs created with the Version 4.01 or 4.02 packager. You must repackage all ICs, and thus shapshots, using a Version 6.0 image.
