Batch m3u playlist creation for all folders
I've been trying to find an easy way to do this, but I can't seem to find exactly what I need. I just want a simple way to:
  • go through all my folders recursively
  • for each folder with mp3s and oggs, making an m3u for each
  • have the m3u in the actual folder, not the root folder
  • name the m3u just like its containing folder.

Any help is appreciated.

This script should sort you out:

Code: [Select]
Const ForReading = 1, ForWriting = 2, ForAppending = 8

delete = false
set args = WScript.Arguments
if args.Count > 0 then
    if LCase(args(0)) = "-d" then
        delete = true
    end if
end if

set fso = createobject("scripting.filesystemobject")
wscript.echo WriteM3u(fso.GetAbsolutePathName("."), delete) & " files written"

function WriteM3u(path, delete)
    dim count
    set fso = createobject("scripting.filesystemobject")
    set fdr = fso.GetFolder(path)
    if fdr.SubFolders.Count = 0 then
        m3u = path & "\" & fdr.name & ".m3u"
        if fso.FileExists(m3u) then
            if delete then
                wscript.echo "... deleting existing file"
                fso.DeleteFile m3u
            else
                wscript.echo "... renaming existing file"
                fso.MoveFile m3u, m3u & ".old"
            end if
        end if
        wscript.echo "... writing """ & fdr.name & ".m3u"""
        set m3ufile = fso.OpenTextFile(m3u, ForWriting, True)
        for each f in fdr.Files
            if right(f.Name, 3) = "mp3" or right(f.Name, 3) = "ogg" then
               m3ufile.WriteLine(f.Name)
            end if
        next
        m3ufile.Close
        count = 1
    else
        count = 0
        for each subfolder in fdr.subfolders
            wscript.echo "Searching """ & subfolder.path & """"
            count = count + WriteM3u(subfolder.path, delete)
        next
    end if
    
    WriteM3u = count
end function


Just save it to "WriteM3u.vbs" and stick it in the root directory of your mp3 and ogg files. To run, type:

Code: [Select]
cscript WriteM3u.vbs


By default it will rename any existing m3u files it finds. If you would rather delete them, just add "-d" to the end of the command-line, i.e.

Code: [Select]
cscript WriteM3u.vbs -d

TAG can also do this from the command line. I use Speek's tag frontend, as the number of switches can be quite intimidating.

Yeah, thanks, it's awesome. If you wrote it yourself, maybe you could help me make one modification to it? It doesn't work right for albums with multiple CDs, because my folder structure for them looks like this:
Foldername\Disc 1\
Foldername\Disc 2\

Right now the script writes:
Foldername\Disc 1\Disc 1.m3u
Foldername\Disc 2\Disc 2.m3u

Is there any way to make it write (ideal):
Foldername\Disc 1\Foldername (Disc 1).m3u
Foldername\Disc 2\Foldername (Disc 2).m3u

or:
Foldername\Foldername (Disc 1).m3u
Foldername\Foldername (Disc 2).m3u

or even:
Foldername\Foldername.m3u (with files from both folders)

This would make the script supremely useful for me, hope you can do it

No problem zambaretzu. Try this:

end if

set fso = createobject("scripting.filesystemobject")
wscript.echo WriteM3u(fso.GetAbsolutePathName("."), delete) & " files written"

function WriteM3u(path, delete)
    dim count
    set fso = createobject("scripting.filesystemobject")
    set fdr = fso.GetFolder(path)
    if fdr.SubFolders.Count = 0 then
        if len(fdr.Name) = 6 and left(fdr.Name, 5) = "Disc " then
            m3uName = fdr.ParentFolder.Name & " (" & fdr.Name & ").m3u"
        else
            m3uName = fdr.Name & ".m3u"
        end if
        m3u = path & "\" & m3uName
        if fso.FileExists(m3u) then

Thanks a lot masterofimages.

There's still a small issue: for some albums, I have artwork, stored under \Foldername\art\. The script writes an empty \Foldername\art\art.m3u but no \Foldername\Foldername.m3u like it should.

Thanks for the great script!! Is it possible to make it name the playlists Artist - Album.m3u using the name of the album's containing folder?

I had been looking for an automated way to create folder based  playlists for over 4 years. Today I got lucky and came across this thread. The script kindly shared by masterofimages worked beautifully and solved my problem.

Thank you so much.

It would be perfect if the files were order by name.
This script produce a caual (not ordered) list of mp3 files inside the folders, producing an inconsistent playlist.

I would like to add my thanks to masterofimages

Here's a variation of their code that:
  • generates a playlist for a folder containing audio files where those folders also have subfolders that contain audio files. The original script only generates the playlist for the deepest folder (that had no further subfolders). I've simply commented out the if count statement and endif for this aim.
  • indents the log output according to depth of the folder
  • searches for flac audio files too (m3u playlists can be used with these file too)

Found this nice script, but missed the sorting of dirs. So I included it (and created an account for this site, which annoyingly took me somewhat longer).

Furthermore I suppressed all the requesters for each subdir (I do want to sort some hundred dirs!). You can reactivate them by the verbose flag (-v) in the command line. Or just change "shutup = false" at the beginning of the script.

Be aware I used the last script, but didn't check much. There are some funny commented lines...

Here comes the code:

Some days later I didn't find an edit button any more... so here comes a new version which should work better.
(I did include a "option explicit" and didn't check it properly as I was running an old version... sigh).

Improved the flag parsing and added a "prefix" constant for naming of the m3us if someone is interested.
