=====================================
I’ve been able to delete folder/files held by N360_BACKUP by changing file permissions.
I’ve needed to opt Give access to => Remove access
right click Folder/File => see menu item Give access to => then Remove access => then Stop sharing => then Change settings => then try Delete (you may see UAC prompt)
