If you're providing a consumer storage service, and users are uploading their own data for personal use, this is outside the remit of GDPR.

If you're providing a storage service to a business that handles personal data, your a data processor, not a data controller.

If you're the data controller, you need a classification technology that can identify personal data in those documents (amongst other capabilities).

As always, there are exceptions, but that's the general rule.
