re-export multiples modules under a single alias in Typescript

I have several files (modules) exporting objects and functions:

directory/
--> FileA.ts
--> FileB.ts
--> FileC.ts

My goal is to re-export all these functions/objects from all these files under the same alias. What I would like to do is create a new file AllClasses.ts that re-exports everything under the same alias.

Wrong example 1 of ./AllFiles.ts:

export * as AllClasses from 
    './FileA.ts', 
    './FileB.ts',
    './FileC.ts';

Wrong example 2 of ./AllFiles.ts:

import * as ClassA from './FileA.ts';
import * as ClassB from './FileB.ts';
import * as ClassC from './FileC.ts';

export {ClassA, ClassB, ClassC} as AllFiles;

I have searched on StackOverflow, Typescript Handbook or other websites for a similar way to do that but couldn't find any.
