I don't seem to be able to us the "Cut" command on a file in the Finder, like you can do in Windows Explorer on Microsoft Windows. (In Windows, once you select a file and "cut" it, you can then move to a different directory and "paste" the file to that location.)
The only way I can move a file using keyboard or contextual menu commands is to copy the file to another drive or location and then delete the old version of the file.
In the Finder's 'Edit' menu, 'Cut' is in the list but if a file itself is selected, it is always greyed out. 'Copy' is not. Why is this?
