I subscribe to the jackrabbit mailing list and this response made me think.. Why?? Using a
check sum to build a folder structure.?. Shouldn't the folder structure be understandable...
If that is recommended... I really must have missed the purpose of jcr...

Indeed, just about all the advice out there is "go deep" instead of "go
wide".  One possible way to do that would be to calculate, say, and MD5
checksum from the file (its name, or its contents, whatever), and take
the pairs of digits and make each of those pairs a folder.

Example:  an image named "blub", gives an md5 hash of
455523d86a8a1ab7c7d33208fe0219e7, which would yield a folder structure of

You could take them in groups of three, or four, or you could only go so
far with it (not using the entire checksum) -- whatever you like. 
Regardless, you ought to be able to get a reasonably balanced tree over

Just my two cents...
