Chapter Seven – FastCD

Other Applications
When you build a virtual CD image, you can opt to build the
image in either a compressed or a non-compressed format.
Compressed images are created using a proprietary format
and are saved with an FCD file extension. Non-compressed
images are created using the standard ISO 9660 CD-ROM
format. They are built by performing a sector-by-sector copy of
the CD-ROM and are saved with a CDR file extension.
.CDR – Standard sector-by-sector copy using ISO 9660 format
.FCD – FastCD's proprietary image format using data compression
Sharing a CD-R Image File
FastCD virtual CD images come in handy when you want to
share a pre-mastering CD-Recordable (CD-R) image. With the
virtual CD on the network, everyone has access to it and can
preview it before it is recorded to a CD-R.
Some recording software products support building an image
file using the standard ISO 9660 CD-ROM format. Any of
these products can be used to create a CD-ROM image that
can be used with FastCD.
FastCD recognizes only those files that have the CDR and
FCD extensions. Image files created with other software pack-
ages will have different extensions, so you will have to rename
those files and give them the CDR extension before you can
reference them with FastCD.
FastCD keeps track of the virtual images it creates by listing
them in the the FastCD configuration file, DPFASTCD.DAT.
This file is located in the server's DiscPort NLM directory:
sys:\system\discport\discport.cd\dpfastcd.dat.
The names of the new image files must be added to this con-
figuration file, if you manually create them through means
other than native FastCD. You can use a standard text editor
to make the additions to the config file.
