Deleting files from Collaborative space

Hi i am Abhishek Jadhav from Team Kratos Racing working on vehicle Harness in these applications Electrical system Design, Electrical 3D Part Design and Electrical 3D Design. 

While working on this i uploaded some data by mistake in collaborative space , now i want to delete the unwanted data but if i am selecting more than one file, i can not see the delete option.
Please suggest me a solution for this as deleting each file individually is taking longer time.
Thank you!
