im sure this thread will help you on some of the frequency thing you
asked for

for the file itrating in the directory for the corrasponding file (i
hope i understood what you want to do...) you can do so with the
"File" class

http://java.sun.com/j2se/1.5.0/docs/api/java/io/File.html

it represnet a Entity in the FileSystem (File, Dir and whatever)
you will find these methods usefull:
isDirectory()
isFile()
list()
list(FilenameFilter filter)
listFiles()
listFiles(FilenameFilter filter)
getPath()

after you got all the files into object just parse the relavnt data of
each path from each file (the File.listFiles() method return a
File[] ) and search for the corresponding file at the other File[]
for the reading part just use a bufferdreader (http://java.sun.com/
