As with any virtual file system that is configured on top of the PublishingFileRepository, you must add the custom VFS to the list of VFSs that are managed by the /atg/epub/version/VersionManagerService.

In the FTPFileSystem example, this step requires you to add /mycompany/FTPFileSystem to the VersionManagerService’s list of VFSs.

For more information on the VersionManagerService and completing this step (including a configuration file example), see Configure the VersionManagerService in this chapter.
