I am new to Macs and so I may be the one missing something here instead. My internal HD is around 300 GB on my Mac Mini. I use it as a high resolution music server with just about everything being stored on external drives. My internal HD is now just about full and I can't figure out why since I do not store data there, and I can't locate the data that is shown to be there. My internal HD is shown to be at 280 GB. Just about all of that is located in the User folder under my user icon since I am the only user. 100 GB is located on the Desktop where I do have some files temporarily stored. In adding up the contents of all the other folders under my User icon I only have another 20 GB, or so. There is another 160 GB of data in there somewhere, but where? What am I missing here, besides that data? Where else should I look? Thank you.
