Based on what little you have told use, this is not a "VERY Huge" data set.
In z/OS, the only"file" is the data on a magnetic tape between the beginning of tape and a "file mark," or the data on a magnetic tape between two "file marks." Period. End of story.
A named collection of data on a disk volume is a "data set." There is at least one difference between a "data set" in z/OS and a "file" as used in Windoze or *nix: a data set consists of records that have a defined format. The data in a "file" is a stream of bytes with no defined format.
