podcast app that can play downloaded podcasts trasferred from PC

I am new to Android, coming from iPhones. I am after an app or a way that can allow me to play podcasts that I have already downloaded on my PC. In itunes, I just drag and drop the podcast episodes into the iPhone and the Podcast app automatically sorts and displays them ready for playing. All the ones I've tried for Android (i've tried about a dozen of the free ones), but none seem to offer this functionality. They all offer to subscribe and download directly on my phone. To sum up: I just need to play the files transferred from a PC, not download them, as I manage all my music and podcast from a central PC. I have tried just dragging the files inside separate folders into the phone, but they come up all jumbled in the music player app, though at least organised inside the folders. Any suggestions on APPs (ideally free ones as all I really need is an organiser style APP, nothing fancy) or even tweaking existing Android apps. Thanks in advance
