Where are custom resource label values stored in Sitefinity?

Custom resource label values in Sitefinity are stored in the file system, specifically under the App_Data folder. This is because Sitefinity allows for localization of resource strings, enabling developers to provide customized labels and messages in different languages or for various contexts. These resource labels are generally managed within the appropriate folders in App_Data, where they can be easily accessed and modified without direct database operations. This approach also facilitates easier version control and deployment, as the localization files can be included in source control repositories.

Storing them in the database or directly in widget configuration files would not provide the same level of flexibility that the file system allows. The App_Data folder serves as a central repository for data that needs to be modified or maintained separately from the core database content. Thus, by keeping custom resource labels in this location, Sitefinity provides a more manageable and efficient solution for localization.
