Sample code to either Calculate size of all files or Export Files from a web

I wrote the following code awhile back to export files from a corrupt site.

I also found it handy to calculate the size of a web (And see where the biggest web is in a site collection) to get around the following : (Error Messages When You Delete or Rename a Folder or Site in Windows SharePoint Services https://support.microsoft.com/default.aspx?scid=kb;en-us;827930 )

Hope this helps you, and you can use it for other apps as well!
