WLM: How do I select more than one email message (without individually clicking each one while holding CTRL)?

Hello,

I imported hundreds of emails in many different folders to my new PC. The old emails are now in STORAGE FOLDERS>IMPORTED FOLDER. Now, I need to move them into proper folders (inbox, drafts, etc). So, I know I can click on a message and "move to" a new folder, but.......like I said there are hundreds of emails. Is there any way to "select all" to highlight? If I click each one individually, my finger will fall off. Thanks.
