Movefile doesn't have access to directory

I'm trying to rename a file, and no matter what I try MATLAB won't let me.

>> cd 'C:\Users\Jack Walsh\Downloads'
>> movefile abc.txt xyz.txt
Error using movefile
Cannot write to destination: C:\Users\Jack Walsh\Downloads.  Use the 'f' option to override.

What can allow me to write to the Downloads folder?

'xyz.txt' is an invalid option.
