Better way to extract files that doesn't need processing about binwalk HOT 2 CLOSED

You should be able to use the existing --dd option to do what you need; to extract only JPEG files:

 $ binwalk --dd='jpeg:jpg' file.bin

To extract everything:

 $ binwalk --dd='.*' file.bin

Hi. What about file sizing? For example, some piece of results:
7418159 0x71312F HTML document header
7428508 0x71599C HTML document footer
7428597 0x7159F5 HTML document header
7433720 0x716DF8 HTML document footer
7433802 0x716E4A HTML document header
7436683 0x71798B HTML document footer
7436770 0x7179E2 HTML document header
Scannig says, that 71599C file have to take 89bytes, but extracted with dd option takes 646328. Thiese are concatenated files. Is there any way to determinate, where is beginning/end of each file? This suggest me a second question. This result is from firmware, for cable modem. I have here a one big file extracted froma lzma block of data. As far as i know, lzma is not supporting to compress multiply files into a one file. How can i extract it properly? I mean to split each file in exact point?
