Open both workbooks, use Window / arrange / tiled. Now click on a cell in
one, type = and then click on a cell in the other. You just created a link.
Close the workbook you are linking to and you will now see the full filepath
in the formula. You can now copy this down as far as you like.

How do I enter it in? If I enter it as a list it tells me the formula is
invalid. If I enter it as a data validation list it says that I can't
validate outside data.=

Use a range in the drop down list workbook that directly references the
range
in the 'closed' workbook, i.e.,

='[other book.xls]Sheet1'!A1
='[other book.xls]Sheet1'!A2

These formulas will work, even with 'other book.xls' closed, and use this
range of formulas as the list for your dropdown

I need to have a file that stores a list of projects. This file will be
updated on a regular basis. In another file I need to have that list
populated into a drop down selection. When the user opens the file it
should
auto update any changes to the project list that is in the different
file. I
have tried to do it using data validation but it will only pull the
values in
if I have both files currently open. I would like to have the project
list
file closed on a network and have the other sheet still pull the info
in.

How can I get this to work?
