How to insert the downloaded file into minecraft.
Texture Packs-
1-Open Minecraft and click on "Texture Packs and Mods"
2- Hit "Open texture pack folder"
3-While that is open, go to the downloaded file in another window and either copy and paste or drag and drop into the TP folder.
4-Right click on the zip file and select "Extract Here", which extracts all files inside into the same folder. You can delete the zip afterwards if need be.
5- Make sure there are no extra files in the folder, just the TP you want.
6- It should be in your Minecraft Texture Pack Menu, just select, click "done" and you're ready to go!
Maps-
1-Open your start menu and type "%appdata%" (without queries) into the search bar.
2-Look for the folder that says ".minecraft".
3-Once inside that, click on "saves".
4- Go to the downloaded file in another window and either copy and paste, or drag and drop into the "saves" folder.
5-Right click on the file, and select "Extract Here", (same as texture pack tutorial).
6-Make sure the (Map Name) folder has been extracted, then delete the zip file. Either that or move it out of the "saves" folder.
7-Just launch minecraft, click Single Player, and it should be in there! Ready to play :)
