Recently I came up with an idea of making my own program for tagging mp3 files. I realised I'm lacking in knowledge. For now I need the following information:
1. After typing a path to a main folder, I'd like to read the names of the folders inside.
2. Than I want to visit each of those folders - get inside (Those folders will include mp3 files).
3. Finally I want to enter this section of a mp3 file where the information about e.g. atrist or genre is kept and I want to chane it.
Can anyone help tell me with this?
