How do you label revised audio drafts?

I am sorting a folder of generated song drafts that accumulated over several months. Repeated titles and vague filenames make it difficult to tell which export belongs to which version. My first step is preserving the originals and recording the purpose of every proposed revision. One phrase I searched for was [url=https://repairsuno.top]remove suno artifacts[/url] but those words alone cannot show whether a revised recording sounds better. Is a folder structure, a filename convention, or a spreadsheet easiest to maintain over time? I also need a way to distinguish a format conversion from a change made to the audio itself. For each file I can record the export date, source version, format, and reason for keeping it. I would rather maintain a small useful record than a complicated system I stop updating. Please share a naming example that would still make sense when reopening the folder next year.
