Off-line Web Browsing & Downloading Files
By John Anderson
October, 2000
The Internet represents a vast storehouse
of information and software. Some people are simply overwhelmed by the
amount of data (information) contained on the Internet.
If you only have one phone line in you home
you know that anyone trying to call you will get a busy signal, so people
may tend to be 'stressed' when surfing because they know the clock is
ticking. Often, the best web sites are so large that sitting and reading
all of the material is simply not possible in a single session.
This article will explore ways to lessen
the impact of on-line surfing by showing how it's possible to save
something for viewing at a later point in time.
Saving information
You've found a site that contains
information that you find extremely useful, but do you have to return to
the site every time you need to reference the information? No! A little
known feature of most browsers is the ability to load and view web pages
off-line. One thing to keep in mind, while you can view a web page
off-line, unless you reconstruct the structure you won't see the images
for the page. With that said, here are some the steps you can follow in
order to save a web page and view it off-line in Navigator 2.0, or
Explorer.
Click on File Menu.
Select the option "Save as..."
(Explorer users! Use "Save as File..." option.
Save the file, but remember the file name!
This will allow you to save the file to
your local hard drive. Normally the files are named using a four character
extension (.html). In the case of both browsers, the program will know,
and use the file name under which it was stored on your system.
Viewing a Document Off-line
Once you are disconnected from the
Internet, activate your browser.
Navigator 2.0
Click on the "Open File..." menu
option under the "File" menu and move to the appropriate
directory where you saved the html file.
Select the file that you wish to view from
the list supplied and it will appear in the main display window.
Explorer Ver 3.0
Click on the "Open..." menu
option under the "File" menu.
Either type the filename, including the
full path of where you saved it, or use the "Browse" feature in
this dialog box to move around your hard-drive until you locate the file.
Select the file that you wish to view from
the list supplied and it will appear in the main display window.
Viewing a file, which you have saved to
your hard-drive, as opposed to viewing it on-line poses a few unique
problems. While you may have saved all the pages in a website any links on
your saved page that lead to a different website will not work unless you
are online. Clicking on them in an off-line mode of operation will not
harm your computer or damage any of the saved files in your computer.
Saving a Graphic
What if the page uses graphics to supply
important information? Did you know you could save that image on your
computer?
Save a graphic file is very easy.
Navigator
Position the cursor over the image and
click on the right mouse button.
Select "Save image as..."
Enter an appropriate file name for the
image.
Click on the "OK" Button.
Explorer
Position the cursor over the image and
click on the right mouse button.
Select "Save picture as..."
Enter an appropriate file name for the
image.
Click on the "OK" Button.
Make sure you use either a ".GIF"
or ".JPG" as the file extension.
Downloading Programs
Downloading is used to describe the process
of obtaining software from an external computer into your own local
computer.
Downloading software can consume a
significant portion of your on-line time. Many downloadable files are
large and take a while to retrieve. Files that you download can be
anything, from new software and upgrades, to multimedia audio and video
files.
Before you begin create a directory or
folder and call it "Download". This way you will always know
where to put a file you get from the net and easily locate it when you
need to.
Download Identification
Once you have downloaded a file, the next
step is figuring out what to do with it. In many cases all you need to do
is click on the file and it will begin the installation process. In some
cases you won't be so lucky.
The important thing about the file is the
extension. The extension is the part following the period (".").
For example, some files may have a ".zip" extension. This
identifies the file as an archive file.
An archive is a single file in which one or
more files have been stored. Not only can multiple files be grouped
together but the files are usually compressed so that aver all you have a
smaller file to download as compared to downloading each file separately.
It is very possible to download an archive that is one megabyte in size,
only to learn it contains as much as ten megabytes of compressed files.
You will need a special program that is
capable of opening the archive.
Once you have completed the installation
you will be able to delete the archive.
