VCFGZ

vcfgz is a term used in computing to denote a compressed package that carries configuration data. There is no single, official specification for vcfgz, and the meaning can vary between projects. The term is sometimes encountered as the filename extension .vcfgz or as a project label in documentation.

Typically, a vcfgz file is a gzip-compressed bundle that packages configuration files and a manifest. Some implementations layer a tar archive before compression (tar.gz), while others use a single gzip stream containing a JSON, YAML, or XML configuration. The accompanying manifest often records the version, compatibility, and a list of included files.

Common use cases include provisioning and migrating settings for embedded devices, network appliances, virtualization platforms, and software deployment pipelines. The approach aims to simplify transfer and integrity verification of configuration state across environments.

Because vcfgz is not standardized, different projects may prescribe different internal layouts and validation rules. As a result, interoperability is limited to project-specific tooling that understands the particular vcfgz flavor in use.

In summary, vcfgz represents a flexible, project-dependent approach to packaging and transporting configuration data in a compressed form. Related formats include gzip, tar, and common configuration formats such as JSON, YAML, and XML.
