What type of software is used to bundle several files into a single package for email transmission?

Compression software is designed specifically to reduce the size of files by encoding the data more efficiently, which can facilitate easier and faster transmission, especially over email. When multiple files are bundled together and compressed, they occupy less storage space, which is particularly useful for sending large attachments or a group of files simultaneously. This can enhance the speed of the email transfer and ensure that the files remain organized in a single package, such as a .zip or .rar file.

In contrast, encryption software is intended for securing data by converting it into a coded format to prevent unauthorized access, while antivirus software focuses on detecting and eliminating malware to protect systems. File recovery software is used to restore lost or corrupted files, rather than to package them for transmission. Each of these alternatives serves distinct purposes that do not apply to bundling files for email.
