## Digest and Message thread

Digest and message threads are distinguished by the subject text. When creating a followup message most e-mail clients will add the text `Re:` in front of the existing subject. For example, this means is that if the first message in a thread has the subject text

> Difference between OS/2 and Windows-NT

then a followup message would have the subject text

> Re: Difference between OS/2 and Windows-NT

and a followup message to the first followup message would look like

> Re: Re: Difference between OS/2 and Windows-NT

This added text invalidates the ability of various e-mail clients to sort messages by subject. Power Listviewer removes all leading text which matches `Re:` from the subject. This transforms all the subject texts in the previous example into

> Difference between OS/2 and Windows-NT

Power Listviewer can then use the subject text in order to match up messages into threads.

Note: If the subject text on one of the messages has been changed in any way it will show up as a separate message thread.
