Hi! Best Page/Design File Practice

Hi Figma Community!

I would just like to ask for your thoughts, and perhaps suggestions on what could be the best practices for when we create a design file:

Is it advisable to create pages for subtopics for that particular design file?
– Design File: Event Collaterals
– Pages/subpages would consist of:
---- Event 1
---- Event 2
---- Business Cards
---- Posters
---- Signage

→ would this make the design file heavier should there be more than ten pages with plenty of assets per page? Or is this okay in building more pages?

The reason for this idea of putting all collaterals in one design file is for organizational purposes - so they’re easy to find should we need to add more for a particular client.

Looking forward to hearing some suggestions for this!

Thank you!
