Structure of a Virtual CD Container
You don't really need to understand how these files are structured in order to work
with Virtual CD. But for those who are interested, the following provides a brief
description of virtual CD container files.
Each virtual CD consists of 2 or more files:
• The container file, with the extension .VC4, which indicates the data
structure of the virtual CD
• Virtual data CDs contain one or more files with extension(s) consisting of
sequential numbers, from .000 up to .999, which contain the actual user
data. These are especially important for DVDs, because when the FAT32
file system is used (which is most often the case), file size is limited to 2GB,
while most DVDs contain larger volumes of data. In such cases, user data is
divided into a number of separate files. The container file keeps track of the
structure so that the virtual CD driver "knows" how to put them together in
virtual CD form.
• Virtual audio CDs contain a number of audio files, depending on the number
of tracks included from the source CD(s).
Installation
If you are updating an earlier VCD version, you need to deinstall the older
version and then restart your system before installing Virtual CD v4. When
you deinstall the old version, the program asks whether you wish to delete
existing virtual CDs. Make sure you don't inadvertently delete any virtual CDs
that you wish to convert for use with the new program!
Place the installation CD in a CD drive and wait a moment for Windows to detect it.
If the autostart function is active, the installation begins automatically, starting with the
"Welcome..." window.
If installation does not start automatically, double-click on "My
Computer" in your Explorer and then on the symbol for the drive where
you inserted the installation CD.
Now you should see the contents of the installation CD. Double-click on the
"SETUP" file to start installation.
Follow the instructions as the Wizard guides you through the installation procedure.
The program asks, for example, whether you wish to retrieve audio CD information
over the Internet. Please do not answer "yes" here unless your computer has Internet
access.
