I have a small txt file that I'm using to store saved game information.  Right now I'm saving it to the root of the SD card(no folder).  Should I create a folder(with the name of my game) if one doesn't exist and then save the file in the folder?

Is there a folder that is typically used for these files(kind of like how Windows has the 'Program Files' folder)?

Use Shared Preferences. Android will save everything for you. You can store almost anything inside and it is easy and fast to save/load.
Check this oficial guide for more information.

Save:
1  
2  
3  
4  
5  
6  
String lvl_name = "level 2";
int lvl_id = 2;
SharedPreferences.Editor saveLevel = getSharedPreferences("levels", 0).edit();
saveLevel.putString("level_name", lvl_name);
saveLevel.putInt("level_id", lvl_id);
saveLevel.commit();


Load:
1  
2  
3  
SharedPreferences loadOptions = getSharedPreferences("levels", 0);
int lvl_id = loadOptions.getInt("level_id", 0);
String lvl_name = loadOptions.getString("level_name", "name");

One of the most important reasons to use preferences is that they are per-user.  In Android 4.4 (could be earlier, too) devices like tablets can have multiple users.  If you just write to an external directory they will all share the same save game data.

Thanks to both of you for answering.

What about Apple IOS?  Is there also a Shared Preferences?
