If it is a scammer, some of your questions will be ignored. Try to ask them again if you are not getting any answer 70 percent she is a scammer.
And generally scamming done in semi automatic way. Send same e-mail twice if you are getting 2 different answer most probably it is a scam. If love words started in second e-mail it is scam again.
Another method could be googling e-mail texts and file names she sent to you(Scammers use exactly same text for many people). There are forums against scamming, if it is not something so new some other people may share it on those websites.
if she asks you for any financial help before you meet in person - assume it's a scam
If she asks for any financial help before meeting, it is definitely scam.
If one or two of the above fits your case it means it is scam, it is not hard to understand, you can easily understand it in 2 e-mails.
