>>>>>>Hi,

>>>>>>I have about 11 GB of MP3 files on my PC. They are all in subfolders of a parent folder \music.

I think I know how to connect an iPhone to the PC (via USB cable). But I am not sure if I can create a folder on iPhone to copy all these files. The iPhone has about 70GB free so that space is not a problem.

It took me a while but finally I figured how to transfer mp3 files from the PC to the iPhone's VLC app. It works now!
Thank you very much for recommending the VLC!
