A Newb's Dilemma: Bulk Conversion of WAV to MP3

[Cohen's Ghost]

I'm a newb and was gifted an external hard drive with 400+ CDs recorded as WAV files with Windows Media Player 7.
I want them all on my phone as mp3s (while maintaining the originals) and obviously want to batch convert as simply as possible.
The path is G: Data > Music > Phil > a folder for every artist > folders for every disc by that artist > individual song files. Questions:
Can you simply feed dbpoweramp the “Music” folder? Or the “Phil” folder?
Does dbpoweramp extract the individual discs/song files making this a single-step process? If not, do I have to feed it every disc folder to convert, then create new folders for every disc as an export location?
IOW, how the heck does it work?

Use Batch Converter, you would want to preserve the folder location if writing to a new location such as:

[origpath]\[origfilename]

as the naming then set a new save location.

I can get as far as selecting “Music” to convert to mp3s, then I’m stuck on the Output Path. (See image.)
I simply don’t know what those choices mean. Ideally, I’d to duplicate the path stated in my OP, changing “Phil” to Bill.
Since I can’t get past this, I have no idea what comes next and there is no tutorial.

Click Preserve Source Path and choose a location you want to save to.

I can get as far as selecting “Music” to convert to mp3s, then I’m stuck on the Output Path. (See image.)

Choose 'Edit Dynamic Naming' and on the subsequent screen set:

Base Location: G:\Data\Music\Bill\
Dynamic Naming: [TRIMFIRSTFOLDER][TRIMFIRSTFOLDER][TRIMFIRSTFOLDER][origpath][][][]\[origfilename]

Each "[TRIMFIRSTFOLDER][]" removes a leading folder from the original path [origpath], so nesting 3 removes Data/Music/Phil.

Hope that makes sense.
