7z format often saves more space than ZIP. Users handling big datasets, installers, or backups usually repack the ZIP into 7z for storage benefits.
The easiest way I’ve found to switch large ZIP archives into 7z is using reliable archive converter software. I use Softaken Archive Converter Software—it lets you add single files or entire folders, pick 7z as the output, and keeps all your folder structure and metadata intact. The batch conversion is fast, even for huge archives, and there’s no data loss. This archive converter software makes the whole process simple and stress-free.
