Hi, Klaus !
GoogleV is a program written for show (and save in it's cash) satellite images from GoogleMaps.
There is a similar program GoogleMV that do the same and stores downloaded images "as is", for example trtqrsr-image is contained in directory 07 (it's the length of trtqrsr) with the name trtqrsr.jpg
So it makes about 24 directories, and the more level - the more images stored in directory.
That way makes some problems - on PDA I cann't keep tens of thousands of images in 1 directory because of card file system limitations.
The GoogleV uses another way - every level consists of 4 images (q.jpg, r.jpg, s.jpg, t.jpg) and 4 subdirectories q, r, s and t. So it makes a tree of about 23 levels (the first level t is absent, so trtqrsr keeps in r\t\q\r\s\r.jpg) That format is much more suitable for PDA, to my mind.
I put an example of GoogleV tree in zip-archive.
All theese programs can be downloaded with no problems.
The only 1 minus of GoogleV is that it doesn't supported now, while GoogleMV stil grows
Anyway GoogleV has quite enough functionality for all needs.
And by the way, there are scripts to export from one format to another
