The first step in extracting a CFG file is to open the file with Notepad. Go through the CFG files and note the number of lines it has.

On a computer that has a CD ROM drive, you will see the text "FILE ENTRY". There are only two options here - to change the file extension or over write the existing file. Which you choose depends on your needs.

In order to change the CFG file extension, simply delete the text after the file extension. This is usually followed by one of these two letters. For example, if you have an existing file with the name CFG.CFG, then you can simply delete the word CFG. You will find that the extension for this new file is "CFG". Get more interesting details about open cfg file check this site.

If you would like to overwrite the existing file with the new one, then insert a blank CD into your computer's CD ROM drive. Then use the "O" key to open the menu and select "File".

Once you open the menu, you will see a list of file extensions. You will want to look for the file name that you want to change or overwrite. Enter the CFG extension in the box at the bottom of the screen. You can also use a backspace key to manually delete any spaces.

When you select this option, you will be given the option to either move the cursor to the end of the CFG file and press "Shift+Delete", or press "Ctrl+Backspace". If you prefer the backspace key, you can press the '' key simultaneously.

On a computer that has a CD ROM drive, you will see the text "FILE EXIT". Here is where you can actually remove the old file.

If you would like to overwrite the new file, then again, insert a blank CD into your computer's CD ROM drive. Then use the "R" key to open the menu and select "New". Select the option to either overwrite or remove.

Now you will find that you have the option to either move the cursor to the end of the new file and press "Shift+Delete", or press "Ctrl+Backspace". If you prefer the backspace key, you can press the '' key simultaneously. If you select the option to overwrite, then you will need to use the "O" key to select the option to overwrite.
