Why can't I play Skyblock on my laptop?

I have already watched numerous YouTube videos about it, but when I inserted the Skyblock file into the Minecraft saves ordener it did not change.

Can someone tell me why?

I'm playing on a Lenovo laptop in case that helps.

LG and thanks for every helpful answer!

What do you mean Do you have your own server?

What kind of file is that? A file? Then the map may be in the folder. If it's a ZIP file, you'll need to unzip it first.

You probably haven't unpacked the downloaded world yet.

Uhh…

OK, how do I unzip a file?

At WinRAR right click> WinRAR> Extract here.

With 7zip right click> 7-Zip> unzip files…

Of course, you have to install WinRAR or 7-Zip beforehand, if you don't already have it.
