p7zip is the 7zip implementation of 7z for windows. My knowledge is |
| 11 |
based on the Linux version. Both version should create |
| 12 |
compatible arcgives. Look at the manual: There are several options to |
| 13 |
increase compression ratio. For me -mx=9 (1GB RAM needed) works fine. |
| 14 |
7z for windows should have equal/identical/similiar setting available. |
| 15 |

The compression ration of (p)7zip using LZMA compression is far better |
| 17 |
than that of gzip -- and it costs more time to compress... |

7z x -so win98.7z | dd of=/dev/(win98) |

...then try 7z/p7zip. |

Ony my two cent -- your mileage may vary... |

Keep hacking! |

PS: p/7zip is GPL'ed. Highest compression ratio for lowest price, |
| 36 |
hehehe :) |
