Can you continue to play in the Minecraft trial worlds if you get the full version?

I tried Minecraft recently, and I'll get the full version for Easter. I've already found a place where I want to live and started building. The trial version has now expired and I can't change anything. My question now is whether if I get the full version, I can then continue to build on the test world as normal or whether it will then be gone forever and nothing more can be changed.

If you press the Windows key + R, enter% appdata%. Then you go to the folder. Minecraft, then in the folder saves -> see picture, then you select the folder and copy it e.g. To the desktop and then you copy it to the saves folder of the full version.

Umm, what is a world folder, sry am a beginner XD

Don't know, try for Windows:

Win + R

Type:% AppData% \. Minecraft

See if there's a folder: Saves.

If so, then I think you can keep your worlds

Look, I added the answer.
