– use DOS line-endings (CRLF)
– first line is #EXTM3U
– list files one per line
– use DOS directory-separator – \
– one way is to use filenames relative to the directory
containing the playlist
– this works for both onboard files and the microSD
– blank lines and comments starting with # are allowed

so something like this works in either \MUSIC\ folder :
(where ^M represents a carriage return
- as shown with cat -v )

#EXTM3U^M
dir1\dir2a\my-song1.mp3^M
dir1\dir2b\my-song2.mp3^M
dir1\my-song3.mp3^M

So my only remaining question is how do I mix
onboard files with files on the microSD card ?

Thanks for listening,

You say that I can use EasyTag to write a playlist for the
e280v2 I just bought on eBay. But there are quite a few
options in easytag:
Eg, relative/full-path, DOS-separator, list/info …
Also, are there any headers needed (lines starting with #) ?
And are DOS line-endings required?

Could you please post just small examples of working M3U lists.
Could you please post a few small examples of working
M3U lists: I would love to see one for the onboard files,
one for the microSD card, and one mixed if that is possible.

Thanks so much for the article, but I sure could use just a bit
more help.
