Folders or Channels [Sync]

Hello Bubble.

We are small company with about 30 employees. We use OneDrive for our project.

We are active in the sewer inspection industry.

Since we sometimes exchange small projects, we have the problem that when we do it via the “Main Channel”, the files/folders are synchronized for all workers. This is rather suboptimal. Hence my question.

Would you create a separate channel for each employee or a “project handover” channel and the employees' sub-folders in it, with approvals only for the correct colleague?

The aim should be that when employee 1 uploads the project, it should not be synchronized with everyone, but only with the colleagues who either have the approval for this folder or channel.

Thank you in advance.
