Cannot delete .band files from desktop
I was working on a file in GarageBand, I saved the .band file on my desktop, but after I quit GarageBand without saving the work, the .band file went a little weird. I tried dragging it to the trash and cmd-delete it but the message came up saying "The item “Recording Final.band” can’t be moved to the Trash because it can’t be deleted." Later I launched GarageBand again, and when I tried to drag the weird .band file from desktop to the GarageBand icon on my dock, the dock appears to crash, my wallpaper went gray for a second and then the dock came back up. Also when I select the file and hit space bar to do a quick look it shows up saying No Items Selected. I like to keep my desktop tidy don't want these files here blocking the way. Anyone knows the solution to the problem?
