+## Hidden files
+
+By default hidden files will show for users with `com.apple.finder AppleShowAllFiles`
+set to `TRUE`. This can be worked around by moving all hidden files outside the initial
+window size, this has the side-effect of enabling a scrollbar.
+
+Files to usually move:
+
+- `.background`
+- `.DS_Store`
+- `.Trashes`
+- `.VolumeIcon.icns`
+
