Hello, This is probably another silly question on my part, but I want to be sure before I delete something that I need. I just got done with the semester of school and I am trying to make some spare room on my hard drive by deleting all the papers I have written, homework, etc. I am coming across all the old .dmg files for the applications I have downloaded in the past couple of months in my downloads folder. I just want to make sure whether or not it is okay to delete these files and that it won't interfere with the apps I have now. Thanks!
