Helping with deleting content in Kodi on a NVIDIA Shield TV

[AC Question]

Just bought a Shield box to run Kodi and cannot get it to delete files that my previous box (a cheap android box) wrote onto the hard drive using Kodis File Manager. I can get file browsers from the play store to do it, but not Kodis File Manager. Gives the error "Failed to Delete at Least One File..." Etc. Any help would be greatly appreciated.
