the usage of 'any chance'

  Yesterday,I got a replying email from http://argouml.tigris.org,there is a phrase in the email,It is 'any chance' in 'Any chance of a zip, or just the zargo?',I don't know the meaning of 'any chance'.

  I searched the internet and got some explaination.

  1.'what is your work exactly, if there is any chance for u to be interested telling me that?(一般人不会在交谈的开始就把自己的职业告诉对方),I think this is a euphemistic asking.(This sentence come from:http://www.zzwb.com.cn/news/2005-01/31/content_129725.htm)

  2.by any chance(ask or request some thing civilly)

   for example:Could you please lend me your car tommorow,by any chance?

  So,I have seen his meaning is:Give me a zip or just a zargo file.
