A temp directory is just a folder that you can delete later on.
All you have to do is create a new folder. You can do this anywhere, but go into My Documents, then right click on a clear space, then got New, then Folder.
This will create a new folder which u can rename to whatever you want. When you're asked to copy whatever to a temp directory, you copy the files into this folder.

When you're finished with the patch, you can delete the folder and it's contents, cos it's only temporary.
