I don’t know how I did this.
I had previously dragged and dropped all my files in folders onto the player or used WMP but always in MSC mode.
Last night I was able to make a new playlist by browsing to the folder and highlighting the files, then right clicking and choosing “create playlist”
After that, I added some more music and let the player sync while I slept.
I woke up and I got the “Not enough space for music db, please free 90MB”
Problem was that when browsing, all of the files had disappeared and couldn’t be viewed to delete anything.
I ended up going into MTP mode to delete them through WMP. But then when I went back to MSC mode, all of the files were still invisible.
I can’t work like that. That’s why I use MSC mode in the first place so I can reorganize folders as needed.
I found I couldn’t do this anymore so I reformatted the player in the settings.
I had a backup of the music that was on the player so after reformatting, I was able to simply drag and drop my backup onto the player, let it copy, and all is well.
BUT now I can’t create playlists the way I could last night! If I switch to MTP mode, the files are invisible. When in MSC mode, I right click the files but there is no “create playlist” option.
