NTFS was not availabile under windows 3.1 I know this because I was there. Windows 95 not windows 98 can "see" NTFS partitions. (Inded Windows 95 can only see FAT16 partitions, with a maximum size of 2Gb). Windows NT was the first OS to use NTFS by default.

SQLite databases are used by many programs including several forensics tools, e.g. Autopsy 3. SQLite 3 is current and older SQLite packages cannot use sqlite3 databases so use sqlite3 tools.

Contents

SQLite3

SQLite version 3 uses a page-based storage where the pages are used for various types of data e.g. there are:

  • lock-byte pages
  • freelist pages
    • freelist trunk pages
    • freelist leaf pages
  • B-tree pages
    • table B-tree interior pages
    • table B-tree leaf pages
    • index B-tree interior pages
    • index B-tree leaf pages
  • payload overflow pages
  • pointer map pages

Write-Ahead Log (WAL)

The default method by which SQLite implements atomic commit and rollback is a rollback journal. In version 3.7.0 a "Write-Ahead Log" option was added.

Use Cases

Web Browser Data

Mozilla Firefox and Google Chrome both use SQLite version 3 databases for user data such as history, downloaded files.
