Where to Find OneDrive ADMX and ADML Files

ADMX files (Administrative Templates) are XML files used to define Group Policy settings in Windows environments, and can also be uploaded into Intune for policy management.

Combined with ADML files (the language files), they enable centralised management of client workstation configuration. This article explores how they work, their structure and their integration with Intune.

ADMX contains the parameter definition (registry key name, data type, etc.)
ADML contains localized strings displayed in the Group Policy Editor (GPO) console

OneDrive ADMX/ADML

The ADMX/ADML file can be found on Windows using the OneDrive client:
%ProgramFiles%\Microsoft OneDrive\<build number>\adm\

The OneDrive.adml file located in the root folder is the English file and must be placed in the en-us folder.

Sub-folders correspond to localized folders for each language. For example, the folder for French is named fr instead of fr-FR. Note that the folder names have not been renamed to match the ADML folder names used in GPOs, so you will need to rename them manually if necessary.

I maintain a list of ADMX/ADML files on my github if you need:

There are many versions available, but my GitHub does not contain an exhaustive list of all ADMX files. I update the repository approximately once a month.
