How to use QML Playlist Type save function to save playlist.

[iamRahul]

I am unable to use Playlist save function to save playlist of my Music Player made in QML.
I already have tried using the function, but the operation always fails.

FileDialog {
        id: filesLoader
        title: "Chose files to add to playlist"
        folder: shortcuts.music
        selectMultiple: true
        selectExisting: true
        nameFilters: ["Mp3 Files (*.mp3)"]
        onAccepted: {
            audioPlaylist.addItems(fileUrls)
            if(audioPlaylist.save("file:///E:/Playlist")) {
                console.log("Playlist Saved")
            }
            else {
                console.log("Playlist Save  Failed"+audioPlaylist.errorString)
            }
            
        }
    }

I dont know why. May be because of providing wrong location parameter in the syntax
bool Playlist.save (location,format)
Syntax Link
I checked the documentation of Playlist Type but it does not mention any guidelines about how and what type the location is required.
I can use FolderListModel, but I want to explore Playlist Type if useful.
Please help me.

@iamRahul I figured it out. We need to specify full location path till the file, and specify file type in format. Then it worked for me.

            if(audioPlaylist.save("file:///C:/MyMusicPlayer/Playlists/global_playlist.m3u","m3u")) {
                console.log("Playlist Saved")
            }

Adding the filename global_playlist.m3u and format m3u made it working for me.
