How do I transfer maps from a Mac to my PC?

I recently got a PC better suited for games than my MacBook Air. In the process, my maps will not show up in the single player map selection menu.

I copied all of the data onto a flash drive, copied it onto the PC, installed Minecraft. The maps appear in the folders but not in-game!

No files are zipped!

What can I do to get these maps working?

Make sure the maps are in this folder:

Yourname>appdata>roaming>.minecraft>saves.

P.S. I also play minecraft and have created a .minecraft library for ease of access, but it is entirely up to you if you want to do this.

P.P.S. The dot in .minecraft is important, it is not a mistake. If you are having trouble finding the folder, you can also search for it but from my experience, it takes a little time.

Hope this helps, DM01131
