On the matter of “obscure” files/file extensions, Labnol.org (Digital Inspiration tech blog) always drudges up great, usable ideas. Here’s a related article:
From a Mac forum on iPad backup issues (http://www.mobileread.com/forums/showthread.php?t=109833):
Problem – I have upwards of 3000 photos on an iPad and as this link discusses, to extract the content once”backed up” presents a problem.
What is a “.mddata”?
Every forum on iPad backup gladly references the file location for Mac OS or Windows. For Mac it is ~(home directory)/Library/Application Support/MobileSync/Backup/.
But does anyone know how to get at the data and use it on the computer without transferring it back to the iPad? I can’t see the purpose of such a backup if the data can’t be read by my computer! Short of SQLite or some back-end tricks I don’t know what to do…
The photos are digitized family photos; some dating from the early 20th century and are invaluable.
