File type/kind

anyone know the four letter extension assigned to classic and OSX apps? i'm trying to find a way to exclude them from a backup set.

    Well, I'm pretty sure that Mac OS X applications are actually folders (packages, to be specific) with the extension ".app". As for Classic apps, I'm not sure ? I don't have OS X installed on my system yet.

    An easy way to see what the file extensions are is with the terminal. To see OS X app extensions, type:

    ls -a /Applications

    To see Classic app extensions (if they even exist), type:

    ls -a "/Applications (Mac OS 9)"

    Hope this helps!
