Customize the Files Detail Page
Make files work better for you by customizing the fields and layout
of the Files detail page. Choose from standard fields to show when the file was last updated,
file size, file type, and more. Create custom fields and buttons to track metadata specific to
your business, to use in validation rules, and provide data for searches and reports. This change applies to Lightning Experience only.
Use record types to customize the layouts of different record types based on what’s needed for that type of file. Combine customized file detail pages and record types with validation rules to turbocharge the quality of the file data in your org.
Note
To see the Files Detail Page, set up at least one custom record type in addition to General, the default type.
