In addition to extracting things like icons and other images, this can also be used to "hack" programs. Of course you have to know what you're doing, and the hacking is the sort where say, you might change one string to another.

Years ago when I was playing a DOS game called Demon Stalkers (see https://en.wikipedia.org/wiki/Demon_Stalkers) I hacked the program so that it didn't always check the disk it came on. Basically I replaced "A:\ " with "C:\DEMONSTLK"! Best to backup first!!!!
