Hello accmailers ...

We have had many requests for more information about how to use
www4mail to download and join large binary files.

So here is a full worked example: downloading Pegasus Mail.
The example assumes you are using the Windows operating system.

====================================================================
1. DOWNLOADING AN 'UNZIP' PROGRAM

First -- do you have an unzip program on your computer?
www4mail 'zips' most binary file downloads to make them smaller, so
you must have some way of unzipping them to their original format.

If you do not have an unzip program, do this now ...

Send an email to www4mail`at`szs.net
In the body of the email, enter
http://www.math.hawaii.edu/lab/197/unzip.zip

www4mail will return to you an email with a large attachment named
'unzip.zip'. Save this attachment to a folder on your computer (we
suggest you name this folder 'binaries').

Rename the saved attachment from 'unzip.zip' to 'unzip.exe' (because
it really is an executable file).

Now you have an unzip program.


====================================================================
2. DOWNLOADING PEGASUS MAIL

This is worth doing, because Pegasus Mail is the email client we
recommend to people using www4mail and other email-only methods.

The size of Pegasus Mail is about 7 Mb. It will arrive in your inbox
as multiple emails, each with a large attachment -- so before you do
this, please make sure your remote mailbox is empty -- download
everything.

Send an email to www4mail`at`szs.net
In the body of the email, enter
ftp://mirror.switch.ch/mirror/pegasus/winpmail/w32-441.exe

www4mail will return to you 35 emails, each with a large numbered
attachment: w32-441.exe.zip.001 to w32-441.exe.zip.035.

When they have all arrived, save all the attachments to your
'binaries' folder.


====================================================================
3. JOINING THE ATTACHMENTS

Your binary download has been split into 35 separate files, so now
you must join them again. It is very easy to do.

In your 'binaries' folder, create a new text file named 'join.bat'.
Enter the following lines in the new file ...

  copy /b ^
  w32-441.exe.zip.001 + ^
  w32-441.exe.zip.002 + ^
  w32-441.exe.zip.003 + ^
  w32-441.exe.zip.004 + ^
  w32-441.exe.zip.005 + ^
  w32-441.exe.zip.006 + ^
  w32-441.exe.zip.007 + ^
  w32-441.exe.zip.008 + ^
  w32-441.exe.zip.009 + ^
  w32-441.exe.zip.010 + ^
  w32-441.exe.zip.011 + ^
  w32-441.exe.zip.012 + ^
  w32-441.exe.zip.013 + ^
  w32-441.exe.zip.014 + ^
  w32-441.exe.zip.015 + ^
  w32-441.exe.zip.016 + ^
  w32-441.exe.zip.017 + ^
  w32-441.exe.zip.018 + ^
  w32-441.exe.zip.019 + ^
  w32-441.exe.zip.020 + ^
  w32-441.exe.zip.021 + ^
  w32-441.exe.zip.022 + ^
  w32-441.exe.zip.023 + ^
  w32-441.exe.zip.024 + ^
  w32-441.exe.zip.025 + ^
  w32-441.exe.zip.026 + ^
  w32-441.exe.zip.027 + ^
  w32-441.exe.zip.028 + ^
  w32-441.exe.zip.029 + ^
  w32-441.exe.zip.030 + ^
  w32-441.exe.zip.031 + ^
  w32-441.exe.zip.032 + ^
  w32-441.exe.zip.033 + ^
  w32-441.exe.zip.034 + ^
  w32-441.exe.zip.035 ^
  w32-441.exe.zip

The caret character ^ at the end of all lines except the last is a
continuation character, and must be included.

Now, while in the 'binaries' folder, open a command window and enter
  join
 
It will join the attachments to make a new binary file named
'w32-441.exe.zip'.


====================================================================
4. UNZIPPING THE ZIP FILE

While still in the command window, enter
  unzip w32-441.exe.zip

It will de-compress 'w32-441.exe.zip' to make 'w32-441.exe'.
That is your download -- the latest version of Pegasus Mail.


====================================================================
5. NEXT EXERCISE: DOWNLOADING PEGASUS MAIL DOCUMENTATION

The english-language manual is a zipped pdf document. If you have
successfully completed steps 1 to 4 above, you should be able to
obtain it by accmail methods from
ftp://mirror.switch.ch/mirror/pegasus/manuals/WinPMailManual-441.zip


====================================================================

Finally: this worked example is all in english. If anyone has the
time to translate it into any other language, it is certain that
your fellow subscribers will be grateful.
