.DS_Store is the name of a file in the Apple OS X operating system for storing custom attributes of a folder such as the position of icons or the choice of a background image. The name is an abbreviation of Desktop Services Store, reflecting its purpose. It is created and maintained by the Finder application in every folder, and has functions similar to the file desktop.ini in Microsoft Windows. Starting with a full stop (period) character, it is hidden in Finder and many Unix utilities. Its internal structure is proprietary.
