Do I need in each project create a folder/file for each unit/element/modifier BEM?

Always-whether by using the BEM methodology, creates a file structure similar to the tree of BEM, where each block/item has its own folder and a file with the code

If your project is a landing page - you do not need.
If you are doing the frontend of the project logic([though minimal), each module(BEM block) create your css file.
If you create a normal corporate website and in the future will support it - you can just follow the BEM naming, file structure for you would be a waste of time. Consider the fact that many people, so many ways of structuring projects(most often, nobody cares like you do, use DRY)
