Step
2. Decompressing Software Files
The decompression
phase often causes the most confusion for users trying to
install software to their Palm devices. This is usually because
decompression requires additional software and utilizes a
variety of file types that are often unfamiliar. However,
the process is not really that complicated once you have the
right tools and understand what is happening.
Software
files are compressed to reduce their size for easy transmission
over the Internet. In many cases, if the files were not compressed,
they would take hours to download, particularly for users
with slow connections. Once they have been transfered, they
can by decompressed by the user back to their full size and
ready for use.

The first
step in decompressing software is to make sure that you have
a decompression utility. There are a number of alternative
utility programs that will accomplish this purpose, but the
one we recommend is WinZip. If you do not have a copy of this
useful program, click here
to download one (once the download is complete, you can install
and start the program by double-clicking the icon in your
file manager). If you already have a copy of WinZip (or the
utility of your choice) you are ready to start the decompression
process.

Figure 6: WinZip Window | |
Using
your file manager, you will be able to select the file
that you wish to decompress. In this example, we have
gone back into our Palm folder (Figure 5) where there
is a file called 'games' (the file we downloaded from
the Internet).
To
decompress this file, simply double-click it. This should
launch the decompression utility automatically. If you
are using WinZip, you will see a window something like
the one depicted in Figure 6. This window shows all
of the files included in the compressed file along with
certain statistics about those files (such as the file
size and compression ratio).
In
the toolbar you will see a button labeled 'Extract'
(about half way across). To begin decompressing the
files you will want to click this button (if you only
want to decompress certain files you can select those
first by clicking on them, but in most cases you will
want to decompress all the files).

Figure 7: Extract Window | |
Once
you click the 'Extract' button, a window will pop-up
that asks you where you want to save the decompressed
files (Figure 7). You can choose any location on your
computer, but again we recommend using a specific folder
for all of your download files (here we are using a
folder called 'Palm'). You can also create a new folder
to contain only the files you are about to decompress.
This will keep all of your new files separate from other
files you have downloaded which will help keep things
organized and easy to find. To create a new folder,
simply click the 'New Folder' button in the lower left
corner and type in the folder name.
If
you are happy with the location specified in the 'Extract
to:' box (in the upper-left corner of the Extract Window),
click the button marked 'Extract'. Your downloaded file
will now be decompressed and the resulting files stored
in the folder you specified.

Figure 8: File Manager | |
Looking
in the file manager, it is possible to see if the decompression
was successful (in our example you can see that there
are a number of new files listed in the Palm directory
(Figure 8). These are the files that were contained
in the compressed file).
If
the decompression was successful, you can decide whether
you wish to keep the original compressed file or delete
it. If disk space is not really an issue you may wish
to keep the compressed file just in case something happens
to one of the decompressed files and you need another
copy. We generally keep the compressed files in one
folder and all of the decompressed files in individual
folders named after the main program we downloaded.
I
am ready to install. Take me to Step 3.
