Backspace
The keyboard shortcut for going up one level in Windows Explorer is Alt-Up. (Backspace goes to the last folder you were in, but that isn't necessarily one level up.)
If you click on the plus sign in Windows Explorer, then you open it, to see lower-level folders.
Open the start menu and type in %APPDATA% then open the .minecraft folder next go into the saves folder then drop your folder that contains the map in it within the saves Run Minecraft and check if the level name comes up if it does play it if not make sure the map is in a regular folder, not a zip or rar make sure that the level data is not in a sub-folder of the map folder
A sub folder is when you put a folder in another folder and a sub level folder is when you put more than one sub folder in another sub folder.....
Root Folder
In a file hierarchy, a folder inside another folder is called a "subfolder." Subfolders help organize files and other folders in a structured manner, making it easier to navigate and manage data. Each subfolder can contain its own files and additional subfolders, creating a multi-level directory structure.
Compression Software
Brigade is the lowest field command level.
Well You Could Use An Email Account And Attach The Level To It! Or if you're running windows at least (I'm not sure how with Macs) open your start menu and enter "%AppData%" without the quotations, and click on roaming. If you're on an older version than Windows 7 you may have to press "Run." Then find the ".minecraft" folder and go into "Saves," then copy the entire folder of the world you want to transfer to a pendrive or some external memory, and do the same thing except copy the world file in to the new "Saves" folder on the other computer from the external memory.
