on opening spreadsheet a, i am always asked if i would like to update links.
one link reference is to spreadsheet c, which i open and update regularly.
the other is to spreadsheet b, which i haven't used in over a year. is there
an easy way to locate the cell(s) on the tab(s) in spreadsheet a which
contains the link(s)?

it is likely that the update-requesting link to spreadsheet b is no longer
needed, and that i could simplify my process be deleting the cell(s) and
tab(s).

thanks, Jack
