13.5. USB Flash Drives

than a pen.They can be carried conveniently on a key ring, and
are sometimes referred to as 'USB Keys' as a result. These
small drives can contain files, directories, and even software.
Red Hat Enterprise Linux has the ability to use these drives through the
auto-mount features of Nautilus.
