In this mode the resource tree (from a path specified) will be dumped to a single file. You are not supposed to edit these files. Rather you can use this mode to get backups/restore and possibly move a resource tree from one registry to another as an alternative to doing a remote mounting and moving.
The check-in client tool does not support the '&' and 'space' characters, and thereby, you will get errors when resources have these special characters. Therefore, the asset names, which are authorized need to be handled by the check-in client tool as well.
For more information about the Check-in Client see the following pages:
General information about the Check-in Client tool in the Governance Registry.
