13.5. USB Flash
A recent development in removable media is the USB Flash Drive.
This is a small, solid-state memory device, normally no larger 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.
Like diskettes, USB drives are useful for carrying files between
machines not on the same network, or between computers that use
different operating sytems. Linux can read files from a USB drive
formatted to work in Windows. However, if you encrypt the files or
filesystem on your USB drive, Linux may not be able to read those
