Is there any size limiation for a single file?

I am not able detailed specification about size limitation for a single file? Considering I have lots of files including huge binary files around 6G (less or bigger than it), I am wondering RTC supports it or not? Considering there are so many huges files and the total size is increasing to 1-2T, is there any size limitation for RTC respository? I apprecate if there is such specification to refer to?

Thanks for your help in advance.
