Multi-lingual capabilities
It is possible to customize the language of the user interface (as of 24Files v4.360), i.e. of the 24Files component on a record page. The admin interface is available in English only.
In order to customize the 24Files component, navigate to Setup > User Interface > Custom Labels.
Look for the custom labels that start with SharePoint and add your custom translation.
In case you do not see the option to add a translation to a custom label, please first navigate to Setup > Translation Workbench > Translate and activate translation on your ORG.
