1. A computer-implemented method, comprising: presenting a visual representation of a directory level of a file directory hierarchy in an interface, the visual representation of the directory level including a first element representing a first subdirectory level of the file directory hierarchy and a second element representing a second subdirectory level of the file directory hierarchy, where the first and second subdirectory levels are at the same level in the file directory hierarchy; and in response to selection of the first element and then the second element: displaying visual representations of the first and second subdirectory levels together with a scaled version of the visual representation of the directory level, where the visual representations of the first and second subdirectory levels are displayed at a different size and at a different depth than the visual representation of the directory level, and at least one of the visual representations of the first and second subdirectories is partially overlapping the visual representation of the directory level to visually indicate that the first and second subdirectories are below the directory level in the file directory hierarchy, and the visual representations of the first and second subdirectory levels are displayed at the same size and the same depth to visually indicate that the first and second subdirectory levels are at the same level in the file directory hierarchy, where the method is performed by one or more hardware processors.
