The Central Store is a file location that is checked by the [[Group Policy]] tools by default. The Group Policy tools use all [[Administrative Template files (ADMX & ADML)|.admx files]] files that are in the Central Store. The files that are in the Central Store are replicated to all [[Domain Controller]] in the [[Active Directory Domain]].
# Creating a Central Store
To create a Central Store for .admx and .adml files, create a new folder named PolicyDefinitions in the following location (for example) on the domain controller:
`\\contoso.com\SYSVOL\contoso.com\policies\PolicyDefinitions`
When you already have such a folder that has a previously built Central Store, use a new folder describing the current version such as:
`\\contoso.com\SYSVOL\contoso.com\policies\PolicyDefinitions-1803`
Copy all files from the PolicyDefinitions folder on a source computer to the new PolicyDefinitions folder on the [[Windows Domain Controller (DC)|Windows Domain Controller]]. The source location can be either of the following ones:
- The `C:\Windows\PolicyDefinitions` folder on a Windows 8.1-based or Windows 10-based client computer
- The `C:\Program Files (x86)\Microsoft Group Policy\<version-specific>\PolicyDefinitions` folder, if you have downloaded any of the Administrative Templates separately from the links above.
The PolicyDefinitions folder on the Windows domain controller stores all .admx files and .adml files for all languages that are enabled on the client computer.
