Dear Giorgio!
Sorry for the confusion!
There is no real new version of CDFinder. Versiontracker has just picked up the change to the CDFinder Disk Image. I had to modify that because it had contained the wrong Germany license agreement, and for it to be binding, the executable needed a modified version.
So there is no need to re-download CDFinder 5.1.1 if you already use it.
CDFinder
Advanced disk manager.
Version: 5.6.1
