Human Computer Interaction – Assignment 1
In this report, I am the user and the one will do an assessment of those products. It is
obviously that my background is the most important aspect to consider those products are
usable or not. In this case, my psychological profile will be used to describe my
background in order to simplify the connection between my background and my opinions
in this report.

FILE SPLITTER AND JOINER V3.x
3.1
What is FFSJv3.x?
FFSJ is a small program for splitting and joining files, because nowadays, when
people upload or transfer data, they usually encrypt to prevent errors and save
time.
FFSJ was developed by Le Minh Hoang since 2006, but FFSJv3.x was released
since 2007.
The owner has introduced the strengths of FFSJ as below:
-
Very fast:
FFSJ can optimize disk-cache and memory usage, this
makes FFSJ 3-5 times faster than HJ-Split, Win Split, Master Splitter in
both splitting and joining tasks. Of course, it is much faster than any
compression program.
-
Simple:
FFSJ works well on all Windows platforms.
-
Small:
FFSJ are small enough to fit on a floppy disk.
-
Easy to use:
FFSJ has a friendly user-interface; it can be used to split
any file.
12
Human Computer Interaction – Assignment 1
-
Easy to be integrated:
Since v3.0, FFSJ published its
command-line interface. End-users can split/join multiple files using a
.BAT file. Developers can write their own interface (in any language) to
perform splitting/joining tasks from their applications.
-
Secure:
FFSJ uses an advanced encryption algorithm to
make your data much more secure from unauthorized access. Since v2.9,
MD5 checksum algorithm has also been integrated to verify data integrity.
-
Compatible: FFSJ can join parts produced by HJ-Split.
-
Free and Safe:
FFSJ free and clean, it do not contain any form of
adware, spywares, viruses, Trojans and backdoors.
I checked, and most of the above are true. FFSJ can join parts produced by
HJ-Split, if the split parts have the right format extension. FFSJ took 20
second to join 4 parts; each part’s size is 150MB, when HJ-Split took 25
second. FFSJ’s size is very small, only 350KB.
3.2
What task does this software perform?
FFSJv3.x can perform three main tasks: Splitting, Joining and MD5 Checksum.
3.2.1
Splitting
1.
Switch to the "Splitting" tab:
13
Human Computer Interaction – Assignment 1
2.
Select the source file. There are several ways to select the source file:
- Choose the source file from open dialog
- Drag a file from Windows Explorer and drop to the "Splitting" tab
- Edit source file name directly.
3.
Setup parameters according to your preference: change output directory,
change number of split parts, change part limit, etc.
14
Human Computer Interaction – Assignment 1
4.
Click "Split" button, enter your password if you want to encrypt the data,
and wait until File Splitter completed the task. You will see the message:
5.
Done.
15
Human Computer Interaction – Assignment 1
3.2.2
Joining
All split parts must have the same name, except for their extensions (.001, .002,
.__a, .__b, etc.). Joining split parts is equivalent to restoring original file.
1.
Switch to the "Joining" tab:
2.
Select the first split part (.001 or .__a file). There are several ways to
select the first split part:
- Choose the first part from open dialog
- Drag the first part from Windows Explorer and drop to the "Joining" tab
- Edit the first part name directly
16
Human Computer Interaction – Assignment 1
3.
4.
Check the list of split parts from drop-down list.
Setup parameters according to your preference: Change output file,
specify your split parts are in different locations, etc.
5.
Click "Join" button, enter the password if your split parts are passwordprotected, and wait until File Joiner complete the task. You will see the
message:
17
Human Computer Interaction – Assignment 1
6.
Done.
3.2.3
MD5 Checksum
1.
Switch to "MD5 Checksum" tab:
2.
Select a file to get MD5 signature. There are several ways:
- Choose a file from open dialog
- Drag a file from Windows Explorer and drop to the "MD5 Checksum"
tab
- Edit the file name directly
18
Human Computer Interaction – Assignment 1
3.
Click "Get & Copy" button, and wait until File Checksum complete the
task. You will see the message:
4.
Done. MD5 signature has been copied to clipboard, you can paste MD5
signature to somewhere and keep this signature with your file.
3.3
Present one way in which this software is usable for me
3.3.1
Summary of this software usability
FFSJv3.x is a simple splitting and joining files software. Its design has
applied the Nielsen heuristics, the heuristics help the interface of this
software look prettier and easier for me to use.
Nevertheless, I am not the only user of this software. My perspective of it
may not be applied for all other users. Some other can find this software
practically hard to use because they expected a more detailed tutorial or a
system recovery if they make mistake for example. But most of those
problems can be solved without redesign too much.
In conclusion, this program is a usable product.
