The most basic scan for pornography involves scanning for
all files that are images or movies. Then by skimming through
the list you can pick out files by their names (more on this
later).
The most common extensions used
| Images |
.JPG .GIF |
| Movies |
.MPG .MPEG .AVI .MOV |
| Audio |
.MP3 |
To search
for files of these types is simple in Windows. Simply press
your "Start" button and select "Search" from
the Start Menu. Type in the extension of the file format
that you
are scanning for (for example if you are searching for images
type in GIF) and hit "Search Now". Windows

There may be many files that are displayed. Which ones are
pornographic? Double-clicking each one to open it is slow and
laborius. A much quicker way is to look at the filenames. Any
files that have obvious sexual references are immediately suspect.
The next group of suspicious files are those that are named
with seemingly random sets of letters. If you look at their
locations you will also see valuable clues as to what they
are. Double click the suspect names to see what they are.
Learn
to check your browsers "History". In Internet Explorer
there is an icon in your status bar to display the History.
This History lists all the websites that have been visited
recently. It is very easy to clear the history though so do
not rely on this to check if websites have been visited.
There are a lot of ways to hide files on a computer.
Explanations
File formats
Before we
examine this topic I need to make clear the concept of "file format".
Take a normal book that you can read in real life as an example.
The format could be considered the way in
which the words are put together so as to make sense. English
requires certain rules to be kept for the written word to be
understood. Computers likewise have rules for the way in which
data are stored in order to be understood. These rules create
the need for file formats.
File formats
are characterised (in Windows) by their extension. The extension
is the part of the filename that comes after
the "."
The actual choice of extension is actually only of convenience
and doesn't affect the format of the file at all. (compare
it to putting a Japanese cover on an English book to keep with
the previous explanation). To return to the

Searching in Windows XP
Windows XP
has a slightly more complicated search method. When the Search
dialogue appears
select "Pictures, Music, Video" from
the options. When the filename box is displayed key in the *
(asterisk) character. Click here to return >>
