Questions on English Desktop User Manual

I have created a vault in one of my drives in the computer. It also created a network by the same name as the vault I created. My question is, how do you start storing files in the vault? Sorry, I am a first timer. I don’t know what to click. I found a drive with a “d” and “m”. Is that where to store the files?

To add to my previous post, Cryptomator doesn’t reveal my drive also.

Here is a quick guide on how to set up Cryptomator. If you have any questions regarding the guide (watching the video might help), let me know what operating system you’re using and what doesn’t work exactly.
