The OSX "show info" dialog block shows the file size in disk blocks, as opposed to the actual bytes of file content. There might be a misunderstanding between people because the "real" file size is different than the "actually occupied" disk size. This is of course aggravated by lots of small files.

Just to be sure:

    $ du -h -d 0 /Applications/Google\ Chrome.app               
    317M	/Applications/Google Chrome.app

    $ tar -c -f - /Applications/Google\ Chrome.app | wc -c

    $ find /Applications/Google\ Chrome.app -type f -print0 | xargs -0 cat | wc -c

On win8, the total Chrome dir is 450MB, but that includes two versions, and a backup of the installer of the latest. Excluding those and the flash plugin, the running Chrome's (37.0.2062.120) contents are 115MB.
