More About 7z file format

7z is a compressed archive file format that has a .7z extension in Windows. An Archive file is just a file that contains one or more compressed files inside it to reduce size and improve portability/management. 7z files generally have a higher compression ratio than zip files and therefore use less disk space. The trade-off is that it takes longer to compress files to 7z than to zip. Both zip and 7z files can be encrypted but only 7z lets you encrypt the header information of the archive which contains a list of the file and folder names within. Even though you cannot open the files inside an encrypted zip without the password you can still see a list of the files and folder names. Also .7z files are an open file format which means it can be implemented and used by anyone. It supports AES-256 encryption and files size up to 16,000,000,000 GB.
