* Formatting filenames d6c39ae

* docs: update filename guidelines

The directory workflow won't work with the current filename guidelines, and thus will generate a bad-formatted file.

* Update DIRECTORY.md

 #### File Naming Convention
 
-- Filenames should use the UpperCamelCase (PascalCase) style.
+- Filenames should use the snake_case style. This is needed for our workflows to work correctly.
 - There should be no spaces in filenames.
-- **Example:** `UserProfile.ts` is allowed. Do not use `userprofile.ts`, `Userprofile.ts`, `user-Profile.ts`, `userProfile.ts`; these naming conventions are discouraged.
+- **Example:** `user_profile.ts` is allowed. Do not use `userprofile.ts`, `Userprofile.ts`, `user-Profile.ts`, `userProfile.ts`, `UserProfile.ts`; these naming conventions are discouraged.
