Josh's function is pretty speedy. And, if you know you are going to process 
all the files in a directory, then you can store a copy of the detailed 
files before filtering for the specific file you want.

Another way to make quick work of the detailed files is to put them into an 
array:

   put the detailed files into foobar
   split foobar by return and comma

then you can say,

   get item 1 of foobar[urlencode(myFileName)]

to obtain the file size. How's that for a one-liner?
