Do the needful

A search form within an application searches for a data file in wrong location. Instead of folder A, it searches in folder B.

What do you do to fix it? Change the search form?

No.

By Indian logic, you move the file to folder B. If your data cannot be found by crappy search tool, change the data, not the tool And don’t even care that the next application release will again install this file into folder A.
