I am running out of hard drive space on my SSD.  I have discovered that this is partly due to the fact that I have several G of data in my WLM message store.  I have changed this by doing Options -> Mail -> Advanced -> Maintenance -> Store folder and have entered a folder on a larger physical drive.  The messages have moved there fine and WLM works OK.  I have discovered however that my HD usage has not changed - presumably this operation has copied not moved the files.  My questions are:

Is it safe to remove the (presumably unused) message files on my SSD?

Where are these file stored?  I have done a bit of searching on the net and they appear to be in C:Users<my logon name>Local SettingsApplication DataMicrosoftWindows Live Mail.

Is it safe to remove all of these files??

Thanks in advance.
