Before this you should know that anyone who is connected to the same network you are connected to is able to infiltrate your computer remotely and take any file, without knowing even this, who knows maybe you already got this with you but you did not realize? Therefore, in order to avoid the fall of your important files in the hands of others you can simply encrypt them, this will certainly not prevent others from taking the file but will prevent them from reading the content as we said earlier.
First place your important files in a special folder, right-click it and choose
Then click on advanced
Choose encrypt content to secure data Then press ok
In the rest of the windows, just click ok as shown below
So you have finished encrypting the folder, try to read its files on another computer and you will notice that this will not be possible.
