In the Finder, go to the external drive where you want to store your library.

After the move is finished, double-click Photos Library in its new location to open it.
If you use iCloud Photo Library, designate this library as the System Photo Library.

After you open your library from its new location and make sure that it works as expected, you can delete the library from its original location.

In a Finder window, go back to your Pictures folder (or whichever folder you copied your library from) and move Photos Library to the trash. Then choose Finder > Empty Trash to delete the library and reclaim disk space.

Open another Photos library

If you have multiple libraries, here's how to open a different one:
