Smart Project Manager features an own Document Management System
If there's only a small number of documents required during your project, the documents can be stored directly in the database. This is technically the simplest solution.
Most commonly, documents are stored on a file server in defined structures. This storage is supported by Smart Project Manager by default.
Alternatively, standard Document Management Systems can be connected. Smart Project Manager not only stores the files in the DMS, but also creates the required metadata for each document.
