in photos how to fix issue for show referenced file in folder

Which issue are you referring to?

"File > Show Referenced File in Finder" is only working, if you have imported the photos as referenced photos. It does not work for files, that have been imported by copying the files into the Library and are managed by Photos.

If you imported the photos as managed, you have to use "File > Export > Export unmodified original" to see the files.

If the command should not work for files you imported as referenced, Photos has lost the connection and cannot find them anymore. This can happen, if you deleted the originals after importing or moved them to a different file. Then you have to put them back to the place where they originally have been.
