## Remarks

- Requires the system administrator server role (server right `manage_vaults`); a vault
  administrator gets "Access denied".
- Read-only. M-Files Admin uses the folder as the starting value of `Vault.main_data_folder` for
  a new vault (see [CreateNewVault](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCVaultsAdmin/CreateNewVault/index.md)).
