I had a PROBLEM with Windows booting up, but I am able to SEE all of my files when I PUT my harddrive in an external enclosure.  I am backing up all of my data before reinstalling Windows.

Since I can not open any applications, is it possible to backup my contacts, emails, appointments from Outlook and/or Outlook Express?  Where would I find the appropriate files?

Thank you in advance!For Outlook, SEARCH for *.pst.  You should find several files with that extension.  They will probably be at C:\Documents and Settings\username\Local Settings\Application Data\Microsoft\Outlook.  The files you find will be Outlook.pst. archive.pst and maybe backup.pst.   There could be others if you've created a backup under a name other than backup.pst.  RATHER than attempt to describe each of these files, let me just suggest grabbing all of them off that drive if possible.

If you used OE for mail, search for .dbx files and grab all of them.  They contain your OE mail.  If you had an Address book in OE, search your hard drive for  *.wab.
