Thanks for answers.

I'm not going to "touch" that files, I was just wondering why... :)

Tell me if I'm wrong, when I call :

https://xxxxxx:8443/fedora/objects/PID/datastreams/DSID/content

Fedora is reading DSID, calculating hash and "building" the path to get the 
object?

1. hash(DSID) = aa....
2. ""get"" /var/fedora/data/datastreamStore/aa/DSID

Thanks 

Rik
