분할 아카이브
대용량 아카이브를 여러 볼륨으로 분할
7-Zip can split large archives into multiple smaller volumes (parts), making it easier to store them on removable media or transfer over networks with size limits.
You can specify the volume size in bytes, kilobytes, megabytes, or gigabytes. Each volume is named sequentially (e.g., archive.7z.001, archive.7z.002).
To extract a split archive, all volumes must be present in the same directory. 7-Zip automatically detects and combines them.
