index.dat files

When i run CCleaner it shows 2 index.dat files but shows them empty. 0kb 2files

CCleaner never shows anything but 0kb. I have looked at the index.dat files to verify this and they are quite large. Any ideas would be helpful

Thanks

Just reboot and they will be cleaned. CC can't access these files when Windows is running, so they are deleted and recreated at pc boot time.
