Atom editor does not reload changed file
<p>I am using Atom editor on Windows 7. On the git shell when I run the command, <code>git reset --hard</code> ,  all the other editors reset/undo all the modified files. but if I am using ATOM editor, changes are retained. If I try to close the file in editor, Atom ask, file is changed, do you want to save the changes. </p>

<p>How can I force Atom to undo changes when files are modified externally. </p>
