Ciao Matteo,

Since I have not seen an answer to this question, I'll give you my
suggestion.
dir() is a function in the include file files.e.
In library.doc you can read this:

Command: dir
  =

Syntax: =

  include file.e
  x =3D dir(st)
  =

Description: =

  Return directory information for the file or directory named by
  st. If there is no file or directory with this name then -1 is
  returned.
  =

  This information is similar to what you would get from the DOS
  DIR command. A sequence is returned where each element is a =

  sequence that describes one file or subdirectory. =

  =

  If st names a directory you may have entries for "." and "..",
  just as with the DOS DIR command. If st names a file then x will
  have just one entry, i.e. length(x) will be 1. =

  =

  Each entry contains the name, attributes and file size as well =

  as the year, month, day, hour, minute and second of the last =

  modification. You can refer to the elements of an entry with =

  the following constants defined in file.e:
  =

  global constant =

  D_NAME =3D 1,
  D_ATTRIBUTES =3D 2,
  D_SIZE =3D 3,
  =

  D_YEAR =3D 4,
  D_MONTH =3D 5,
  D_DAY =3D 6,
  =

  D_HOUR =3D 7,
  D_MINUTE =3D 8,
  D_SECOND =3D 9
  =

  The attributes element is a string sequence containing =

  characters chosen from:
  =

  d - directory
  r - read only file
  h - hidden file
  s - system file
  v - volume-id entry
  a - archive file
  =

  A normal file without special attributes would just have an empty
  string, "", in this field. =

  =

Comments: =

  The top level directory, e.g. c:\ does not have "." or ".."
  entries. =

  =

  This function is often used just to test if a file or =

  directory exists.
  =

  Under Windows 95, st can have a long file or directory name =

  anywhere in the path.
  =

  The file name returned in D_NAME will be a standard DOS 8.3 name,
  even on Windows 95 or Windows NT. A new long-filename element
  may be added in a future release of Euphoria.
  =

Example: =

      =

      d =3D dir(current_dir()) =

      =

      -- d might have:
{
  {".",    "d",     0  1994, 1, 18,  9, 30, 02},
  {"..",   "d",     0  1994, 1, 18,  9, 20, 14},
  {"fred", "ra", 2350, 1994, 1, 22, 17, 22, 40},
  {"sub",  "d" ,    0, 1993, 9, 20,  8, 50, 12}
} =

      =

      d[3][D_NAME] would be "fred"
      =

Example Programs: =

 bin\search.ex, install.ex

See Also: =

  wildcard_file, current_dir, open
  =

Hope this helps,

Sincerely,
