This section offers FREE files that you may download. These are all freeware
that I use frequently and have found to be useful. I have either found
these in the public domain on the web, created them myself, or compiled existing
data into an electronic format, with credit given within the file to the data's
original author (if known).
Mandatory Disclaimer:
Use these files and programs at your own risk. I have verified that
they're all virus free. I will not be held responsible, in any way, for
damage that occurs from their use.
Spreadsheets for Download
These require Microsoft Excel 98 or later to read. Alternatively,
you can use OpenOffice.org
as a very functional, free alternative to Microsoft Excel. You can use
it to exchange files with people running Word and Excel. It works
under Linux and other OS's to give you a way to use Excel spreadsheets.
