my tool currently does not know how to handle ext4 filesystems. so it will only show you the parts that deal only with ext2 compatible data. the solution: look at how ext4 extends ext2, and implement that. |

more: i did a test. if i got the ext4 image from other system, and when i use ext2rd to extract files from it, maybe i just only get some not all. but if i mount it on some place and umount it, most likely i could get all files using ext2rd, why does this happen and what affects the extraction? |

when you try to extract files from an ext4 filesystem using ext2rd, you will most likely end up with incomplete files. I did not look into what ext4 details are missing. I wrote this tool a long time ago, when I needed to inspect ext2 filesystems on my then windows laptop, nowadays I have a linux laptop, so my need for improving this tool is minimal. |
