exttools

Some tools for reading ext2/ext3/ext4 filesystem images.

I use these mostly to extract files from android system images.

Note that ext4 is not fully supported, some files may not be extracted.

EXAMPLE

This will export the entire filesystem to 'savedir'

ext2rd  system.img  ./:savedir

ext2rd

Usage: ext2rd [-l] [-v] <fsname> [exports...]
     -l       lists all files
     -B       open as block device
     -d       verbosely lists all inodes
     -o OFS1/OFS2  specify offset to efs/sparse image
     -b from[-until]   hexdump blocks
   #123       hexdump inode 123
   #123:path  save inode 123 to path
   ext2path   hexdump ext2fs path
   ext2path:path   save ext2fs path to path
   ext2path/:path  recursively save ext2fs dir to path
note: ext2path must not start with a slash
note2: /dev/rdiskNN is much faster than /dev/diskNN

Build instructions

There are two ways of building extfstools:

• using cmake, actually, invoked using the default Makefile.
  • type: make or make vc for a windows build.
• using make with Makefile.unix
  • type: make -f Makefile.unix, this should also work in windows.
