Nero temp files

I’m trying to clear up some disk space. Can I erase Nero temp files without messing anything up? Like if at some point I may want to burn a project again (i don’t save projects) will erasing temp files damage anything?

any information appreciated. often have problems just when I go to burn, saying there is not enough space in the temp file, but if I clear hdd space it goes ahead. is there any other way around this? cheers ahead of time.
