Help Using Help Reference Back 74 See also "FileSystem alias attribute" on page 76 FileSystem fs class attribute File.fs Folder.fs Description The fs class attribute of File or Folder holds the name of the file system (operating system). Possible values are "Windows" or "Macintosh". Type String; read-only. Example write("The local file system is " + File.fs); FileSystem object File("path"). Folder("path"). Description The FileSystem object contains methods and attributes common to both File and Folder objects. A File object corresponds to a disk file, while a Folder object matches a folder. "FileSystem" is a name used to refer to both Folders and Files. These attributes and methods differ from those found under the FileSystem Class in that they cannot be applied without referring to a particular instance of a file or folder, expressed as a path to that file or folder. You can use absolute path names and relative path names. Absolute path names start with one or two slash characters. These path names describe the full path from a root folder down to a file or folder. Relative path names start from a known location, the current folder. A relative path name starts either with a folder name or with one of the special names "." and "..". The name "." refers to the current folder, and the name ".." refers to the parent folder. The slash character is used to separate path elements. Special characters are encoded in UTF-8 notation. The FileSystem objects support a common convention. A volume name may be the first part of an absolute path. The objects know where to look for the volume names on Mac OS and Windows and they translate the volume names accordingly. A path name can also start with the tilde "~" character. This character stands for the user's home directory (on Mac OS). On Windows, a directory with the environment variable HOME or, failing that, the desktop is used as a home directory. The following table illustrates how the root element of a full path name is used on different file systems. In these examples, the current drive is C: on Windows and "Macintosh HD" on Mac OS.
