How can I delete all Winamp playlists at once? How can I delete all Winamp playlists from an Android device? I currently have to delete them one file at a time.
Long tapping on a playlist brings an option to delete. Looks like you don't want to use it because you've gazillions of playlists.

So, do this: Simply, clear data of Winamp from Settings ~> Applications ~> Manage Applications. It'll make your Winamp install fresh like when it was installed. The only thumbs down thing is that settings of Winamp will be reset to default &amp; you'll need to re-configure them, but its not a big thing.

Update:
After some brainstorming, I found that Winamp stores playlists in a database externally. On my smartphone its: /data/data/com.android.providers.media/databases/external-xxxxxxx.db where xxxxxxx are numbers which are different on two devices I checked.

Use Root Explorer to delete this database after mounting /data partition with R/W access (root access is required).
