Using File Viewer

To help you examine files of various kinds to see what is in them. This might be

in order to see whether they’re really in plain text format
to see whether there's something wrong with them, such as unusual characters which oughtn't to be there
to see whether they were formatted for Windows, Mac, or for Unix
to check out any hidden stuff in there. (A Word .doc for example will have lots of hidden stuff you don’t see on the screen but is inside the file anyway, such as the name of the author, type of printer being used, etc.)
to find strings of words in a database, a spreadsheet or even a program file.
to get certain selected characters picked out in an easy-to-find colour



Here you can see the gory details of the text. Some characters are highlighted in different colours so you can see exactly how the text is formatted.


Loading a "text"

Choose your file – if necessary click on the button at the right of the text-input box.
Press Show.



The two options available are as 1 bytes or 2 to represent each character-symbol in the text in question. You may need to alter this setting to see your text in a readable format.


The two windows

The left window shows how the "text" is built up. You can see each character as a number and, further to the right, as a character.

The right window shows the text, line by line so you can read it. It isn’t an editor and it doesn’t word-wrap.



Just type in the search-word and press Search. The search is case sensitive and is not a "whole word" search.






The colour grids let you see the number section in special colours, so you can find the potential problems you’re interested in.

First select the character you want coloured.
Click the foreground or background colour list change the colour.

The character names are Unicode names. In the picture the symbol with the green background is the last one clicked.



Choose the font and size in the font window. You may need to change font if you want to see Chinese etc. represented correctly.



oYou can set the “hex” columns between 2 and 16.
oThe text can be shown in anything between 10 and 100 columns.
oYou can see the numbers at the left of the main window in hex or decimal.
