    Hello, this may be a dumb question but I was wondering how come when I look at an app in my applications folder and secondary click it to bring up the drop down menu and select get info, the size of the application doesn't match up with what the size says it is on the Mac App store? Non of my apps that I have purchased match up and I was just curios why, everyone of my apps that I have downloaded so far are larger then what it says it is in the App Store. If someone could please answer as to why that is, it would be much appreciated! I hope what I just said make sense, maybe I'm just over thinking it, but just thought I'd ask, i've only had my Mac for about week now.

    Thanks, Jordan

    Never noticed this, but my initial guess is the size in the app store is the package download size, which is compressed and the app installed is the complete uncompressed app and its associated package content.

    That's right, the size shown on store is the size of the compressed download. After download, it is uncompressed and so the size on your disk will be bigger.

    And also Apple changed the way file sizes are shown with some apps (Finder for example) in Snow Leopard

    If I get info on a song in iTunes it is 5.1 meg
    same song is Finder is 5.3

    Downloaded TV show is 175 meg
    In Finder it is 185 meg

    Not sure what way the store works it out, but there are discrepancies depending on how you look at file sizes
