Thanks for the reply, but for some reason btrfs-fins-root does not work on this file system. Here is what I get: [jdg@tiare tmp]$ btrfs-find-root x220_home.img -o 5 Super think's the tree root is at 115230801920, chunk root 131072 Went past the fs size, exiting[jdg@tiare tmp]$ I can mount the file system, access the files, though obviously not the deleted directory.
