Here’s another way posted as an instructional example:
[FINDER] Move Selected Finder Items to Choose Folder Example
Also there is a built in way to move a file I’m finding handy when you have a file open in the Finder.
Clicking on the downward pointing reveal arrow to the right of the file name at the top of the window drops down a menu to rename the file or if you click in the Where: current folder location you can simply click on a folder location listed to select a folder to move to. The second dropdown menu lists your Finder favorite folders so frequently used folder are at hand. At the bottom of the list is an Other… item that when clicked opens a standard nav dialog within which you can get to any folder.
