Using ZIP Archives (for Members of MCS)
The Machine Cancel Society (MCS) offers a number of
documents in electronic formats. This web page describes how to
extract various documents from a ZIP archive.
File archiving is as old as the Internet. One of the earliest, and
longest-lived systems is called ZIP. One or more files are
enclosed in a single file, usually with compression to save
space and connect time.
The Society offers various electronic documents in ZIP format, primarily
to deliver a number of files at once.
When we have ZIPed several files
together in one archive, we call it a "website-in-a-box", a
configuration that makes it easy to view a particular multipart
document using only your web browser without connecting
to the internet.
When you are dealing with a ZIP archive, you cannot
use the enclosed electronic document(s), unless you first extract all
files from the ZIP archive.
For example, we enclosed a number of files for later viewing as a
Barlow's Boston Machine Cancel Exhibit (set 1)
(ZIP file with the exhibit contents).
First of all, when you see a link, such as that listed above, you
want to download the file. The typical way to perform this, is
to right-click on the link, and use the "Save As" (or "save link
as..") menu item that
your browser displays. Be sure to remember where you saved the
ZIP file. If you just click on the link, many browsers
will offer you the chance to download the file. (Some may
offer the option to "Open" the file, while others will immediately
download the file.)
Once downloaded, extracting the contents of ZIP files is
very easy if you are using the Windows (tm) operating system.
Simply double-click on the ".zip" file that you just downloaded. Windows
versions after about "95" will automatically display the "Archive" contents
to you. Copy the files from the content list of the archive to the
desired location on your system. At that point, you can use the
enclosed file(s). See the links near the bottom of this
page for using those electronic formats.
If you are not using Windows, you can still extract ZIP archive
contents. There is a very good free product called 7ZIP, which
has been released for a wide variety of phones, tablets, and computer
and use that product (or App) to extract the ZIP contents.
You can get a free copy of 7ZIP from the website 7ZIP Download. Near the bottom of the web page
are listed the non-Windows systems for which you can get
a free copy of 7ZIP. Follow their installation instructions.
Use your App "store" on the phone or tablet to get the 7ZIP App for
your particular device.
Once you have unpacked the desired file(s) from
the ZIP archive, follow one of these links for
processing of the electronic document:
PDF: (Adobe Portable Document Format) Files
MOBI and AZW3: Amazon Kindle (tm) Book Files
EPUB: Standard Ebook Format Files
NOTE: There is one more "format" we are using, which we call
The example Barlow exhibit link above contains a set of
files that make up a stand-alone web page containing his exhibit
contents. To view the exhibit, you extract the entire ZIP contents
into a new, empty,
folder (directory) on your computer, phone, or tablet. Then,
make your web browser open the "index.html" file in that group of files.
(This is usually the "Open" menu selection.)
Your browser will then become the document "reader" as
you view Bill Barlow's award-winning exhibit. Once the
contents are loaded on your computer, phone, or tablet, you do not need to
be connected to the internet, and you do not need any special
viewer tool, aside from your browser. There are several
such packages stored on the Society's website, and they
will be identified as such.
