n1mm 不支持从cabrillo 格式导入，因为这个格式信息有限，缺太多内容了。

Re: Cabrillo Log Import

Not directly.
There is a workaround that might be usable in some cases. You can import the Cabrillo log into the ADIF Master program (<
http://www.dxshell.com/>), which can create an ADIF file from it. It would be up to you to figure out the correct ADIF tags to apply to each column. You would also have to add some fields to the file in ADIF Master, including the CONTEST_ID field and for many contests, the APP_N1MM_EXCHANGE1 field. But the end result could be an ADIF file that you could import successfully into N1MM+. See the answer to the fourth question at <
https://n1mmwp.hamdocs.com/faq/#other-questions> for some more considerations. After importing an ADIF file, you will need to rescore the contest (e.g. with the Rescore button in the Score Summary window).

大致意思是你要通过第三方的工具先转成adi，同时把一些必要的列内容手工补全，再把这个adi导入n1mm。
希望这个答案能帮到你。
