Detailed information on the b-tree layout is explained at http://sandbox.dfrws.org/2011/fox-it/DFRWS2011_results/Report/Sqlite_carving_extractAndroidData.pdf.

Commercial forensic tools provide support to recover deleted data from SQLite database files, but they don't always recover all of the data, nor do they support extracting...
