SOQL all files in folder

Question

Using Files, is that possible? I've tried:

SELECT Id, (SELECT Id FROM ContentVersions) FROM ContentFolder

SELECT Id, (SELECT Id FROM ContentDocuments) FROM ContentFolder

SELECT Id, (SELECT Id FROM ContentDocumentLinks) FROM ContentFolder

and these queries do not work.

Answer 1

SELECT Id, Title, FileExtension FROM ContentFolderItem WHERE ParentContentFolderId IN (SELECT Id FROM ContentFolder WHERE Name = 'Folder Name')
