Why do we use a zip file?
There are several reasons for using a Zip archive rather than just storing files in a folder, but they all share their ease of use.
Zip files organize data into a single folder that acts like a file, which means you can store hundreds of files and folders in one place without fear of accidentally deleting some of the content. This is common for file backups.
You can also exchange Zip files online to send multiple files to someone at the same time. An alternative is to split multiple emails, one by one, with attached files attached to them everywhere. This is usually difficult to deal with as a recipient and is definitely unprofessional.
The zip file can also be compressed to save disk space, which you should consider if you plan to encrypt a zip file that has many items or a file that contains sensitive files.
Tip: Encryption of ZIP files is limited to these files only. Learn how to encrypt your entire hard drive for even more protection.
