What is AEM's FileVault Tool (VLT)?

VLT stands for the Jackrabbit FileVault tool. The Apache Foundation created a utility that transfers the content of a Jackrabbit/AEM instance to your file system. It performs comparable functions to a Subversion (SVN) client, which is a source control system client. It includes standard check-in, check-out, and management features, as well as configuration choices for displaying project content in a variety of ways. The vault sync service is often used to synchronise repository content with a local file system representation, as well as the other way around. Installing an OSGi service that monitors repository updates and analyses the filesystem contents on a regular basis does this. For mapping repository contents to disc, it employs the same serialisation format as a vault. It's worth noting that the service can only sync with the local filesystem and isn't suitable for remote development.
