How to Encrypt ZIP Files on Various Platforms

We’ve all been there; when there are simply too many files to send, and you don’t want to send those one by one because that’s just way too time-consuming and not to mention gives off a very unprofessional impression.

How to Encrypt ZIP Files

This is where ZIP files come in handy. You can literally just compile or archive all your data or documents in one file and sent it to the recipient.

What exactly is a ZIP File?

A ZIP file is basically an archive file that compresses your data in such a way that you don’t lose any of it.

There are also two types of ZIP files, one of which is the regular non-encrypted ZIP file that can be accessed by anyone when they click on extract files. Whereas, the other type which is the more secure version of a ZIP file is an encrypted file.

An encrypted ZIP file is password protected; this way, it prevents just anybody from viewing your data and permits only a few selected people.

Why Choose ZIP Files?

The most common reason why people prefer to use ZIP files is that they are comparatively easier to handle and are less time-consuming. Since ZIP files compile all your data and documents in one single folder, it is an easier option, and it acts as a free backup file also.

Similarly, as established earlier, it’s way more convenient and impressionable to send multiple files altogether in one small compressed file rather than having to send several attachments.It is also a good option if you’re low on space.

How to Create a ZIP File?

If you’re looking to create a regular non-encrypted ZIP file, you can simply do so by installing any of the ZIP file creating software such as WinZip.

Install WinZip, open it in the WinZip Wizard Mode, and when you’re asked “what do you want to do?”, select “create a ZIP file” then you will be guided throughout the entire process.
