The ListDirectory(dir) calling sequence returns the contents of the directory dir as a list.

ListDirectory accepts two optional arguments: all and returnonly.

all or all = true/false

By default ListDirectory does not display filenames that begin with ".". Specifying the all option makes ListDirectory consider these files as well.

returnonly = string

The string argument is used to select elements from the list of filenames. Only the filenames that match the pattern specified in the string are returned. Patterns of the form defined by StringTools[WildcardMatch] are used.

If dir does not exist, ListDirectory generates an error.

If dir is not a directory, ListDirectory generates an error.
