Another follow up tutorial from How To Create and Send Encrypted E-mail, Messages and Explore Cryptography covering setting up file encryption. After you have installed gpg4win, the package will come with kleopatra installation. Kleopatra makes it easy to do a file encryption. File encryption is necessary if it contains very confidential information.

visit KDE for more opensource and user-friendly application which you can explore and share.
Another important note :

Kleopatra may work with gnupg 1, too but the selftest will
warn about this and some functionality will be unavailable. It should
depend on gnupg2. GnuPG 2.1.x is supported.

However you can do a self test by clicking on settings - perform self test and there should be no error.

Cryptography is a fascinating subject that I'd like to cover more in the future. I have winter holiday and I think I'd be able to cover both technology and other studies. However, without further ado, let's do it!

Steps

• Open kleopatra and click on sign/encrypt

Select a file that you want to encrypt or send to your friend as an encrypted file.

Set up your permission and add another user your wish to share if you already have their public key. You can also tick in encrypt with password but it's less secure. Proceed to click sign/encrypt.

Always remember your passphrase. Like in any other cryptocurrency wallet. You have to remember your passphrase or at least write it down somewhere so you can do the encryrption/ decryption.

Then finally your encryption is done. And now you can share your file only with specific user.

I will be coming up with more noobs tutorial. Nothing is sophisticated if you want to learn. Also, I don't post this via Utopian-io because it's too short and very simple. If you have any questions, requests, suggestion feel free to comment. Additionally here is to the github repository KDE kleopatra.
