How to clean up projects efficently?

Hello everyone,
maybe you know this: In the course of finding ideas you add an endless number of samples and programs, of which you end up using only 10 -20%, if at all, and in no time the memory is full, the projects take forever to load, etc. In short: Overloading the MPC with unnecessary files makes it very sluggish. (Maybe this is just a beginner's thing)

Is there a simple method to remove unused samples, programs, etc. in bulk and thus clean up the respective project?

I haven't dared to do this yet because I was always afraid that I would destroy my tracks.

It would be great if you could tell me the best way to proceed when cleaning up projects.

Many thanks in advance and have a nice weekend!

Purge unused samples.

I know the function "Purge unused samples". Is there also a function for "not used should be unassociated with programs" or do these steps have to be carried out manually one by one?

If there is a function, it would be great if you could describe where or how I can find it?

And just to clarify: A sample is unused when it is no longer assigned to a program, right?

I always thought that a sample is already unused if it is still assigned to a program but is not actively triggered in any sequence.
That would at least explain why I don't get the result I actually want with the pure “Purge unused samples”
