Compressing Music Files For Thumb Drive In Car


I just bought a new Jeep Grand Cherokee and the sound system is excellent.......for a car. I have a ton of music in JRiver, and most of them are large files. I'd like to compress them for my 128 gb flash drive. I think I could fit more music on it, and the lowered sound quality for be fine....because it's a car stereo, right?

Can I do this? If so, how?

Thank you all in advance!

I'm using 32GB USB drive in my Honda Accord. Music is in 256K VBR AAC format and sounds great. The only problem is that Accord does not show directory structure. No matter how many directories I create (Jazz, Pop, Classical) it places all records in one directory in the order they were entered. The only control I have is to advance to next song or record (pretty bad). Because of it I use mostly "random" playback.
Do I need to rip the CDs again through DBpoweramp? I can'f just copy them from my existing library and burn the copy at 320k?
Yes, you can copy from the existing files. Within dBpoweramp there is a Batch Converter. You select the albums you want to convert, select the format you want them in, and select the destination drive and dynamic naming. And that's it.
