Advise on a MP3 encoding tool to reencode all my files

[jamiem1987]

Hi all as per the title could anyone tell me how to best accomplish the following:

I have a folder full of folders of MP3 files, in varying formats but mainly 320kbps, around 70gb's worth.

I'm wanting to re-encode them all in m4a or more efficient codec such as itunes plus as I think I can half the storage whilst retaining quality.

Does anyone know of a tool I could use to do this whilst keeping all ID tags / folder structures?

Many thanks,
Jamie

I'd leave them as mp3 files.

Reason why:
If you choose to re-encode them, you're running them through what is probably a "lossy" encoding process one more time. Every time one does this, one loses more of "the original data" that was in the previous file.
(And, we don't know what would happen to the existing metadata, etc.)

Storage is cheap.
Again, my suggestion is, "just leave them be"...
