Mingalaba! Sorry--I forgot that the folder is only labeled MyDocs in the terminal. The place you want to save them, if you're using the file manager, is the the lowest-level folder, the folder where the Documents, Photos, etc. folders are. Or just save them in the Documents folder and replace the line Code: mv ~/Mydocs/*.ttf ~/.fonts/ with Code: mv ~/Mydocs/.documents/*.ttf ~/.fonts/ in the instructions above.
mv ~/Mydocs/*.ttf ~/.fonts/
mv ~/Mydocs/.documents/*.ttf ~/.fonts/
