The "f" as well as "fn", "d", "dn" and "n" are arbitrary variable names 
without special meaning. The script is mostly a sequence of assignments 
to separate the various parts of each file name. "f" is the original 
file name, "fn" is the file name without path, "d" is the directory 
tree, "dn" is the name of the last directory and "n" is the new file 
name including path.
