Which software to choose for file storage in a small engineering firm (SOHO PDM)?

Question

ownCloud/Nextcloud

I often come across the question - how to organize the storage of files in small offices. For example, in a design organization where there are drawings, estimates, text descriptions. It is desirable to store all this taking into account revisions, to have at least a minimal documentation approval process and to limit the documentation from at least accidental overwriting, deletion (approved - do not touch). The same is true for printing companies.
As a rule, everyone is limited to file storage on the server, at best, slightly delimiting write / read access. It works, but I'm sure there are better options. Indeed, with such a decision, it is difficult to organize versioning, approving, searching.
Conventional workflow systems are difficult to use here, they always focus on complex approval processes, this is a solution for the bureaucratic apparatus. On the other hand, there are PDM/PLM systems for this, but they are terribly expensive. It so happened that expensive CAD systems make expensive and PDM. And again, they are imprisoned for mechanical engineering.
Is there a solution for small offices of 5-20 users, free or relatively inexpensive?

Answer 1

Are you sure you really need it?
A small company - a technical department of 5 designers, a technologist, a standard controller, a chief engineer. Bought SolidWorks PDM for them.
Plus implementation - the specialist set up business processes and the movement of documents.
Plus training - we went for 2 days before tuning, for a day after tuning.
Plus, we bought a separate server for this business.
It hasn't been implemented in a year. As the projects lay in the file storage, they still lie. The server is spinning idle for the second year in the rack.
