Subdirectory Registry

EFI SYSTEM PARTITION SUBDIRECTORY REGISTRY

This is an industry registry of vendor-specific subdirectory names in the EFI system partition described in the UEFI Specification.  The registry aims to ensure fair, orderly, consistent and conflict free naming of files as well as help facilitate industry-wide best practices for the Directory Structure in the EFI system partition.  
 
Originally implemented by the DIG64 Consortium, this registry of vendor specific subdirectory names in the EFI system partition is used to help companies avoid unnecessary collisions in implementation. This list is voluntary and minimally administered. Participation in the Registry or use of this information is at your own risk. 

To register a new subdirectory
