Compressing Music Files For Thumb Drive In Car

Free version of media monkey works well for bulk file format conversions but has learning curve. I used it to covert 1000s of files from wav to flac but does MP3 compressed also.

Dbpoweramp has cost but probably more user friendly. That's what I would use now.

I have a 2014 Grand Cherokee and the manual says that it will accept a 32 gb. card also it will only play mp3 files I created a folder of the mp4 songs that I wanted then converted them to mp3 works fine.

Get dbPowerAmp and compress your files to 320K Variable Bit Rate. This will give you *excellent* sound quality for on the road listening.

And if the 32 GB limit mentioned is true, simply partition your 128 GB flash drive into 4 32 GB "drives" as long as the Jeep's audio player will recognize the 4 virtual drives.

If it won't, then just buy a 32GB flash drive and load your files onto that. I bet a 32GB flash drive costs about $8.00 nowadays...

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.

I already have DBpoweramp...thank you all for the great advice....
