Treating devices as files makes it much simpler to perform raw data operations on them. For example, to make a copy of your hard drive, you could simply do
dd if=/dev/hda of=/dev/hdb
And it would make an exact copy of your hard drive onto another disk.

What folder do you look in for information to modify a device file in Linux?
Answer:Linux and Unix store their devices in /dev. Character and Block devices are there (all devices for that matter).That said, it should be understood that devices are treated somewhat differently under Linux/Unix than some other operating systems. On a Linux/Unix system, all devices are treated as a file, hence the /dev directory and all of the files that reside in it. You may notice that an 'ls -al' listing of /dev produces different output than it does in other directories. Instead of file sizes you'll see the device major and minor numbers. These are represented by the bold type below for the console device.crw------- 1 root root 5, 1 Sep 11 10:41 consoleIf you write a program to open the /dev/console and write to it, whatever is written to the device will show up on the machine's console terminal.
