MacOS file listing through .DS_Store file

.DS_Store” is an abbreviation for “Desktop Services Store”. These files are created automatically by Apples “Finder” software (which is part of their OS).

They store information about the files within a folder, including display options of folders, such as icon positions and view settings.

It may happen that .DS_Store files inadvertently leak filenames such as database backups or private administration panels.
