Link to Parent Folder

Hi all,

I would like to add parent folder links to items in a document library.  I followed the instructions (InfoPath 2007) to use regular expression to replace the file name here:  http://connect.nintex.com/forums/permalink/7012/7047/ShowThread.aspx#7047.   I thought I had it nailed and was whooping it up when I realized that replace text for ItemDisplayName or filename patterns only worked on items without spaces in their names.  Ugh!   I'm using InfoPath Designer 2010.  Does anyone know of a workaround or alternate ways to create a parent folder link?

Thanks!  mjr
