FTP stands for "File Transfer Protocol", and is the manner in which files
are transfered over the internet. File transfer programs using this protocol will be able to
transfer files from
any computer (using any type of operating system) to any other type of computer (using
any other type of operating system).
For our purposes, it is most useful to be able to transfer files from the
Challenge machines "mode" and "pi"
, to the PC's that are commonly found in your classrooms, and vice-versa.
A great file transfer program
is called WS_FTP LE.
You may download it to your PC running windows from here.
Note that the software is only free for teachers, students,
and government employees, and you can go to
Ipswitch (the authors) to download a version other than the one given above.
Once you have installed WS_FTP LE you should fire it up and make a new
connection to mode by pressing the New key on the "Session Profile" window.
Enter the following data
with "ch099abc" replaced with your Challenge login name:
Make sure you press Save when you are done entering the data.
Now, enter in your password in the "Password" box, and press "Ok". You have
now established a connection between your PC and your account on
mode. Next time you start up this software, you can choose "Mode" from the
"Profile Name" Pull-down menu, so you don't have to retype all of the information.
The window on the left contains the files on your PC, on the right are the
files on your mode account.
Now, say for example you wish to get a file from your mode account and place it on
your PC. You would double click on the up arrow and/or double click on the folders
as necessary to browse to the file that you want get. Once you see the file appear in
the window, click on it once to highlight it.
Now, in the other window, choose the
location that you want to place the file into by the same process. Finally click on
the arrow in the middle pointing to the left, indicating that you want to transfer
the highlighted file in the right window to the folder that has been opened in the
left window. Reverse this process to transfer files from a PC to your mode account.
One last bit of information you need to know is related to file type: choose ASCII
at the bottom of the window if the file you are transfering contains only clear text.
An example of this would be a file you've created with Pico. Select Binary if you
are transfering files that do not contain just clear text, such as an image contained in a
".gif" or ".jpg" file.
