Microsoft Word
Spreadsheet document file format
Common extension: .doc
Indicated on this site with the
symbol.
The Word document files require a
word processing program, such as Microsoft Word 97®

Microsoft offers a free Word

The Excel spreadsheet files require
a spreadsheet program, such as Microsoft Excel®,
that can read Excel 97 files.
Microsoft offers a free

can only view the existing spreadsheet. It does not
allow changes to be made and the spreadsheet programming
will not run.
Zip
Compressed file archive format
Common extension: .zip or .exe (for
self-extracting archives)
Indicated on this site with the
symbol.
Zip files are compressed archives
of one or more files. The "zipped" files
may be of any format and may need their own readers,
viewers, or other applications.
To use Zip files downloaded
from this site, it requires a program capable of unpacking
the archive. There are various such program available.
Among the more popular ones are PKWare's
PKZIP® and Nico Mak's WinZip®.
To prepare Zip files for uploading Hazsite
or EDSA7 data, see the Important Notes below.
Zip file may also be turned into
self-extracting archives executable (.exe) files.
These do not require any special unpacking utility.
Just run them in Windows and follow the instructions.
(Hint: Pay special attention to where the self-extracting
archive will place the extracted files. If you want
the files to go elsewhere, specify the location.)
Important
ZIP Notes for Hazsite & EDSA7 Users: While
any Zip-compatible utility program will unpack the
files you download from here, the Hazsite and EDSA7
applications have a special requirement. They need
the DOS version of Zip utilities to work properly.
You can obtain a PKZIP
for DOS®
utility from PKWare. (You may see other versions of
PKZIP utiltiies on the site. Many of them will not
work with Hazsite; we know that the DOS version of
the utilities will work on most systems.)
PKWare distributes its software as
"shareware." Please read the licensing info
for the software and abide by it.
Also, please limit filenames of Zip
files submitted to eight characters (followed by the
".zip" extension).
