Can Office 2013 use my existing Office 2003 documents and emails?

[52yankee]

Like a lot of people I am trying to decide which way to go to upgrade from Office 2003 Basic Edition 32bit. I think the one I want is Office 2013 Home and Business as it has Word, Excel, Outlook etc. What want to know but have not be able to find out through lots of Google searches is this. Will the install of Office 2013 delete all my Word, Excel, and Outlook files? Can the new Office 2013 use all my existing files and email things?

If I uninstall Office 2003 will it delete all my Word, Excel, Outlook contacts, emails etc?
