$   What is the difference (if any) between Lotus 123 worksheet file
$extensions.  I have seen .WKS, .WK1, .WK2, etc.  Does each of these
$extensions have a different meaning?

   The different .wk? and .wr? extensions refer to the file formats used
by different versions of 1-2-3 and Symphony.  1-2-3 and Symphony are
capable of reading each others' formats with the obvious constraint that
they can't read formats that hadn't been defined as of the date of release
of whatever version you're using.  Also, the file translation utilities
supplied with 1-2-3 and Symphony can perform backward conversion (i.e.
taking a more recent format and converting the file to an older format).

$   How can one see what hidden files there are on a disk?  Can they be
$copied (and if so, how?)?

   Hidden and/or system files, in general, are not counted when you use
a filespec involving wildcards (such as *.COM); however, if you know the
name of one, you can type or copy or do whatever to it by providing its
name, just as you can with other files.  For example, if you have a
hidden file called IBMBIO.COM on your disk, along with a bunch of normal
files, COPY *.* a: will not copy the hidden file, but COPY IBMBIO.COM A:
will.

   At the programming level, however, you can force the calls that
search for files matching a given filespec to find hidden or system
files as well as normal ones, and there are several utilities which do
this.  The attrib command that comes with dos can list all files along
with their attributes; see your DOS manual for details.  Many other
utilities, such as PCTools and Norton's utilities, can also show you
what files are on your disk.
