Unlike Windows, Linux stores the programs in a bunch of locations.

/lib, /usr/lib, /usr/local/lib -- for libraries for and from the programs

/bin, /sbin, /usr/bin , /usr/local/bin -- for the program binaries (executables)

/opt -- big stand alone packages.

/usr/doc -- documentation

/etc, /usr/etc -- config files
