more information find in test

I tried pull out the apex file from phone with same apex and compare two files， it seems that the ext2rd exacted apex file added more 00 after the end of apex file ( should be zip structure in the end )， while the same size 00 is before AVB0 tag in the phone pulled apex filed

the AVB0 tag copied

41 56 42 30 00 00 00 01 00 00 00 00 00 00 00 00 00 00 02 40 00 00 00 00 00 00 05 80 00 00 00 02 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 20 00 00 00 00 00 00 00 20 00 00 00 00 00 00 02 00 00 00 00 00 00 00 01 40 00 00 00 00 00 00 04 08 00 00 00 00 00 00 05 48 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01 40 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 61 76 62 74 6F 6F 6C 20 31 2E 32 2E 30

after move those 00 in the end to before AVB0 , the zip is good to open, not sure if some code in ext2rd makes this wrong?

I think the problem is that ext4 filesytem support is known to be broken.
