Delete trashless files from file prompt screen

I managed to delete the number referenced folders and files from the Mobile Viewer folder. Now I can’t delete those files from the initial startup screen. Is there a indexing file that can be edited to correct my mistake. william

Corrected the loss of trash cans under info button
I did this by uploading a same named file to the 3D warehouse. Whether it was this or that the models could not be found, the trash cans returned.
So problem solved, william
