Using SharePoint 2013 are there any file types that can't be checked out and edited?
I was surprised to learn that I could open an Adobe Photoshop .psd file from within SharePoint. After I selected the check out option I was given the Adobe Photoshop icon to choose. I thought only Microsoft files could be checked out.
I know PDF files cannot be edited for obvious reasons. But they can be checked out.
So I ask you again, :) Are there any files that SharePoint 2013 will not allow me to check out?
