How to export a group of brushes?

This morning Photoshop had an update and all my brushes were deleted with that update. I took to sorting the brushes but when I select more of them I don’t have the option to export. When I put the brushes in a folder, I have the option to export the folder, but when exporting it asks me to type in the names of those brushes. That's why I have a folder in folder. How can I avoid that? I want to have only one folder with brushes.
