Whenever I select multiple Excel (2010) files the right mouseclick option 'open' disappears. When I select just one or a few files there is no problem, but from 15 or more files I can't open them at once anymore.
In the picture you'll see there is no 'open' option. Usually this option is above 7-Zip along with 'New' and 'Print'
Can anyone tell me why this is happening and how I can change this?
