Going back to the Mac set-up, I have a pretty old Mac which has a CD/DVD drive.
So I would record into my Zoom H4 recorder, which gave very acceptable quality recordings, transfer recordings to my Mac’s GarageBand for any editing, then copy to iTunes as M4a files. If I wanted to email tracks to friends, I’d make an MP3 copy for smaller file/easier sending. Or I could burn the bigger M4a files to CD.
To find files, they would all be in iTunes.
And yes, I hate OneDrive on my Windows 10 laptop, and will probably switch it off, as it seems to default back to Autosave On without being asked, if I just leave the room for 5 minutes. It completely wrecked an older version of one file which I was using as a template to create a newer version, but wanted to keep the old one too!
