I'm also wondering about this
I have my music in a folder hierarchy on my computer, but I want those files to all be kept in one folder on the device when I sync to it.
Under Preferences, Devices, Settings, I have the media storage folder set to "Music\" which should tell it to put all the mp3s in the one same folder, but when I synced my device it dpulicated the entire folder hierarchy that I have on my computer on the device as well.
The reason I want less folders is my Image Gallery app lists all those music folders as folders with images in them even though I don't want it to, and I'd rather the folders not exist rather than trying to hide all these folders manually one by one in my Gallery app.
Is there a way to remedy this? Thanks in advance.
