Set up custom insert worksheet tab in excel 2007
 

In office 2003 I was able to set up a custom tab on the insert worksheet
which was linked to a defined folder on my computer. I could then put in a
whole load of workbooks in this folder and access them all from this custom
tab (where the folder name = tab name). After moving to office 2007 the
custom tab has migrated accross but the link seems to be pointing to the
wrong / a strange place. Does anyone have ideas where this can be found in
office 2007?
(btw the insert custom worksheet in the help file doesn't answer my question).
Any suggestions appreciated!
