When you insert or connect media such as a CD, DVD, hard drive, or flash drive, to your computer, Fedora automatically recognizes it and makes it available for use. An icon is placed on your desktop and in the
Places
menu in
GNOME
. On the
KDE
desktop an icon is placed in the bottom panel next to the
pager
.
In
GNOME
you should unmount media before removing it from the computer. To do this, right-click on the device's icon and then select
Unmount Volume
or
Eject
, depending on what type of media you are using; during this process any remaining changes to the data on the media is written to the device, allowing safe removal without data loss. Removing media without unmounting it first could cause data to be corrupted; if this is the case, you will not be able to get your data back in the future.
There are several multi-media applications available for
GNOME
and
KDE
desktops. These applications will run in either Fedora desktop environment. To install software packages not already installed, refer to
Chapter 17, Managing software
. You can install applications either by using the
PackageKit
application or on the command line by using
Yum
.
The instructions in this chapter refer to image files at various points. In this context, an image file (or disc image) is an archive file of an optical disc, in a format defined by the International Organization for Standardization (ISO). ISO image files typically have an .iso extension. The name ISO is taken from the ISO 9660 file system used with CD-ROM media, but an ISO image can also contain Universal Disk Format (UDF) file system because UDF is backward-compatible with ISO 9660. An ISO image includes all the data of files contained on the archived CD or DVD. They are stored in an uncompressed format.
In addition to data of the files it also contains all the file system metadata, including boot code, structures, and attributes. ISO images do not support multi-track, thus they cannot be used for audio CDs, VCD, and hybrid audio CDs.
