Compression and Decompression of multiple files

Hi Thomas,

Richard Gaskin, Sarah Richert, yours truly, and others have gotten as 
far as you; but no one I know of has taken the next step: combining 
individual file compression logic with the recursive logic of the 
Transcript Directory Walker.  Sarah & I have done some preliminary 
work to combine her drag-and-drop compression utility, SDB Tools 
compression utility (which, besides simple compression, includes 
logic to default the file type of Windows & Unix stacks for seamless 
transfer to Mac O/S platforms, and prevent the user from 
decompressing a file with a Mac O/S resource fork on a non-Mac 
platform); but it's a VERY low priority for both of us at the moment.

The design I have in mind would create a list of all files & their 
folder locations via a tweaked Directory Walker command, compress 
each file individually, append the individual compressed files, and 
append an index of the archive listing each file's size & byte offset 
from the beginning of the archive file.

Simple decompression would simply decompress the entire contents of 
the folder.  A more elegant solution would display the archive index 
and allow the user to select individual files for decompression
