Yesterday I stumbled across this neat app and great post on Switching To Mac.
One of the great features most modern operating systems offer, and Mac OS X is no exception, is the ability to create a zip archive out of most any document or folder from the Desktop. Simply right-click the item you want to archive, and choose the Compress option from the contextual menu.
There is a problem, however, when Mac users create a zip archive in this manner, then share that archive with users of Windows or Linux. The issue is that there are extra files Mac OS X uses, files that track custom icons and icon placement, that are hidden from Mac users.
