Conversion of zip files to 7-zip file format

zip to 7-zip conversion is essentially repacking of compressed archives. You can easily re-pack various compressed archives from one format to another when you extract the original file (in this case ZIP) and compress the data again to a 7Z format (.7z, 7-zip etc.) Major difference is usually in the compression ratio and thus resulting file size.
