I have an internal 1TB spinner in my 2015 iMac. If I were to get a smaller 250GB internal SSD and chose to store my actual MP3 files (115GB worth) on an external 2TB spinner in a dock station, what would be the best way as to not screw it up? I have self made folder on my desktop called "Music" which is the location/source for the files in iTunes. I assume if I drag/drop this source folder to my external, iTunes on my Mac will be unable to locate the correct files. Is it as simple as that? Just point iTunes to the new drive location but using the same folder name and structure? I won't move files inside this folder around at all. Just wanna drag and drop it. So again, won't be messing with iTunes or the library itself, just moving the MP3 file source folder from an internal drive to external. I've read a few tutorials but most want you to copy iTunes library folder and install iTunes on new drive. I'm not doing all that and not trying to clone anything.
