Probably not. Try using the Office -> Prepare ->
Edit Links to Files command. In the Edit Links dialog box, click Break
Link. Keep in mind that links can occur in places other than formulas.
If you have a chart in your workbook, click each data series in the
chart and examine the SERIES formula in the formula bar. If the formula
refers to another workbook, you’ve identified the link. To eliminate
it, move the chart’s data into the current workbook and re-create your
chart.
If your
workbook contains any Excel 5/95 dialog sheets, select each object in
each dialog box and examine the formula bar. If any object contains a
reference to another workbook, edit or delete that reference.
Choose Formulas -> Defined Name ->
Name Manager. Scroll down the list in the Name Manager dialog box and
examine the Refers To column. Delete names that refer to another
workbook or that contain an erroneous reference (such as #REF!). This
is the most common cause of “phantom links.”
