Dear all,
I recently installed CENTOS7. I find that Some file management functions, such as creating new file, arranging file by size, arranging file by data, etc.,  in the right mouse are missing, and the item "creating new folder is present, but it is grey. 
These right mouse items are availabe in centos 6. How could they be added in Centos 7?
Thanks in advances.
