Well, i don't even want to attempt the above, because it would create so many duplicate files...
This was a great video, but didn't solve my problem.
This one had me really excited, but it didn't work. Not sure if I did something wrong, but the playlist folder it created shows "no file".
Well done on the video. I learned a bit from it for sure. The problem is that I'm trying to import already existing playlists. For example, I have a "chill" list with a few hundred tracks that I listen to with a random mode.
Since making that video I moved away from winamp and use foobar2000, and now I make playlists in an even more manual mode kinda way, what I explain in the following should apply to any music player installed on yer PC (and should help you with getting yer 'chill' m3u file to work).
Ok, so first off, just pretend that every time I say 'AP100' I'm really saying 'Plenue D', because in this theory they should not differ in how they play a playlist. Furthermore, when I say 'fb2k' (foobar2000) please imagine whatever software you use at home on yer own pc/mac to play music and generate/make playlists, the same principle should apply.
The main difference here (in comparison with my video above) is this time I am treating fb2k as a proper music player, the library of music it contains are pointing not to my AP100 (like above in the winamp video) but now actually like how a normal installation of a music software behaves, it's pointing to the library of songs on my hdd on my computer.
So... I load up fb2k and I have already told it to 'search/add' a certain directory on my computer to add that media to my library. I think we can all now imagine that via fb2k I can browse my files like other music software, via id3tags (Genre, Artist, Album etc) or indeed via Folder structure.
By doing this I can build a playlist and save the m3u file whereever I want (desktop). If i want to play that playlist anytime double click it etc, fb2k starts and the playlist shows and works. Follow me thus far?
Now... in comes the portable player part. What I do now with my AP100 is just ensure that before I 'give' that playlist over to it (or make a copy etc) my own AP100 must have a 'strict' copy of the same files and folders as my library on the computer (or close to, I shall explain more about this in a bit). The point is... if I use fb2k to build a playlist containing certain artists and songs that are NOT on the AP100 (or in your case Plenue D), then we cannot at all expect that playlist to work properly! In reality when we ALTER the playlist (these steps still to come) what will happen is it will 'skip over' any song it can't find on the portable player, keep skipping tracks till it finds a track it does have on the player, but the point is to make SURE that both the portable player and the files in the media folder on your computer are the same, especially so for the file structure. If the media library on your pc is 100gb worth of music, but the media library on your portable player is only 95gb, yer missing songs! So use some kind of Synchronisation software to make any updates made to the music library of yer pc mirrored to yer portable player (or the microsd card housed within your portable player. FYI I use 'Create Synchronicity', a simple small program that that can analyse the one data base/folder structure (media library on pc), and if changes are made there apply them to the new folder/structure destination (microsd card). So I do this regularly to make my DAP up to date with what I have at home (good for backup purposes too!).
Now... so what happens is this. You sit down with yer morning coffee. You fire up fb2k (or whatever software you use) and you browse the music library (on yer pc) and you select which songs you want that day. You make a playlist, you save the file (give it a name) and its on the desktop. But... if we drag this file onto your player it won't work, we need to do something to it first.
The m3u file, we right click it and we select 'Open With'>Notepad (I'm using Win10 by the way, mac users will need to do the equivalent). This is an example of what I see when I do mine;

So what can we learn from this? Ok, so my real name is eddie (lol), my music is housed on a G: and my music sits in a folder called 'best of eddie i9 93db' before then being sorted by Artist>Album>Songs.
Now the music on my sd card inside the AP100 doesn't sit in directories like that, it simply is Root>Albums>Artist>Songs. I do it like this because some of the older style mp3 players had problems playing music if the folder depth got too deep, so my sd card is simpler, it's just a basic list of Artist folders and then within each artist folder the albums.
So I use the 'Replace' tool (Edit>Replace). Under 'Find what:' I copy the text 'G:\My Music\best of eddie i9 93db' and in the 'Replace with:' box I leave blank (I don't touch it). I then hit 'Replace All'. Now my playlist in the Notepad looks like this;

I hit File>Save and Exit.
Now, if I drag this m3u file and dump it IN THE ROOT of the sd card directory of where my portable music is, then my AP100 can play my playlist successfully.
With your 'Chill' playlist you will need to do a similar thing. Save it to the desktop (make a copy of it, don't ever mess with your original m3u file in case you stuff up and can't make it even play on your computer ever again!), Edit it with a Notepad, and remove any of the folder structure that points to where it lies on your computer, save it and then dump it on the root of the sd card in your Plenue D.
Now here's where it gets interesting. I have not managed to easily get a playlist to work when music is stored both on the internal memory of a DAP as well as the sd card within, that's because the playlist will need to point to two places where the music file is, and when dumping it (the m3u file) in one place I don't think it can easily do that. I think it theoretically possible, but its a more complicated issue.
I hope this somewhat helps.
