Export doesn't export all emails in the folder... Rated 3 out of 5 stars

Seems like a good tool but I notice that when I select all messages in a folder and export them or do an export of a whole folder, it doesn't export them all. Is it ignoring messages which are earlier parts of other emails? i.e. is it exporting only the latest part of each separate conversation?

For example:
* I email joe@bloggs.com: "Hi Joe, how's things?"
* Joe replies "good and you?" and I file the email into the folder (let's call this email # 1)
* I reply to Joe "not bad, can't complain. What are you doing after work today?"
* Joe replies "I'm working late tonight" and I file that email into the same folder as the earlier one (lets call this email # 2)

Under the above example scenario, does the ImportExportTools add-on only export the email with Joe's second reply (email # 2) and skip the earlier one (email # 1) because it is a part of the later one? I need to know this before we can use the add-on with confidence. Please advise.

This review is for a previous version of the add-on (2.8.0.1).
