I'm probably going out on a limb guessing, but I'll try. If your work with loops or various ideas are fragmented (strewn about on different songs), then unless you save and name them as presets, then they're going to just be all over the place. Basically, the messy room, desk, or file cabinet syndrome.
If I save rendered parts from a loop I've created, I usually look to find another field that I can add what song it's being used with. This helps a lot! Also, if I open the preset later, I'll see it was from a song and not write over it, but rather copy it to modify it further. Software like Arturia have many categories for adding sub names, genres, etc.
Studio One has a helpful sub category as well. There, such as on a preset, I'll add "used on: songname ____________." and add the song.
If you're not working under the guideline of a song, project, or clients project, then you're really doing an injustice to finding your stuff again.
JMO, and maybe you were looking for some other answer. Compliments to your English which seem very good. Far better than my wish of speaking in another language. Someday, zi hope to change that. ; )
