How to play save games data on sdcard so that game can detect it through sd card and

So after so much efforts i could hardly free 1.60gb on my internal memory but still the game's data file is of 2 gb....I have already read about foldermount app but according to it, that app is used to move data file from internal to sd cars and then game can be played, but in my case i dont even have sufficient space to use flodermount...so is there any other way to do this....i have already rooted my phone..:(:rolleyes:
