[Android General] 93Obi:
First of all, clarification:

1.There's a lot of guides showing how to bind large games' .obb files and their respective folders/directories to external sd card. This guide will show you how to install these games even if they are bigger than your internal memory. For example, you got 4 Gb internal SD, on ROM goes 2.5 Gb, and for all your apps, pictures and videos goes 1.5 Gb. It fills really fast, so if you want some HD game, say FIFA 14, you can't install it. Here my guide jumps in.​

2.When a program binds game's .obb data directory (if you have enough memory free on internal SD for the game to install in the first place), its .obb file is indeed transfered on external SD card, but often in memory status there's a bug which still shows it on your internal memory and it is full, but it is not case here.​

You need:

1.Rooted phone, Install from unknown sources allowed

2.FolderMount installed (didn't try with Directory Bind yet)

3.Root file manager like Root explorer installed

4.Game you want to install with .apk +data folder downloaded on your PC

5.Write down or somehow mark names of game's data folder and it's .obb file

So, let's start..

1.Find out where should be game's data folder (in most cases it's Android/obb folder)

2.Copy apk on SD root and folder with .obb files on external SD where it should be installed by default

* make Android/obb folder on external SD if you didn't already​

* for real if it was to be installed on internal memory the path would be: storage/emulated/0/Android/obb/yourgamefolderwithobb​

3.Once copying is done, navigate with your root browser on INTERNAL SD, and make folder named exactly as your game, the one that you wrote down, on exact location,for example storage/emulated/0/Android/obb/ and inthere you make this yourgamefolderwithobb folder (case sensitive!)

4.Now, you get inside this folder that you made with your root file manager, here it is ˝yourgamefolderwithobb˝ without quotes and inthere you make new file named exactly as your game's .obb file, with .obb extension, and save it, for example ˝main.128yourgame.obb˝ without quotes - case sensitive

* if for any reason you can't save your new file, then you make it on your external SD's root and copy where it belongs on internal SD, and if even this isn't possible, then make this file on your pc - new .txt document> save as>all files>exactly named as your .obb and then copy it via USB on your internal SD on the right place, in the right folder.​

5.When all previous steps are done, navigate to external SD root and install your game's .apk . When instalation is done, exit your root file manager.

* DO NOT OPEN GAME ONCE INSTALLED, FOR IT'S NOT OVER YET! Just exit​

6.Go to your MountFolder. On the upper left corner next to ˝List of pairs˝ headline touch menu icon.

7.Once menu open, touch ˝Apps analyzer˝ option. After short scaning, a list of your apps will appear. Search this list for app you just installed. If it's on the list, so far everything is OK, but if it isn't... you probably messed something up, see if you skipped a step or two :P click back button.

8.Open FolderMount again if it exits. Click ˝+˝ option at the top

9.Give name to your game (gta, tenis...) by filling ˝name˝ gap

10.Click ˝Source˝ gap and navigate to internal SD in the game's directory that you made in step 3! By clicking ˝Source˝ you should already be in /storage/emulated/0, it will say at the top the name and the path of your current directory. Once you're in directory you made, click ✓ option at the upper right

11.A pop-up will appear saying ˝Would you like me to create the destination folder automatically? You can choose a custom destination by clicking no˝ Click NO

12.Click ˝Destination˝ gap and navigate in directory that you copied from your PC on EXTERNAL SD in step 2! Once there click ✓ option again

13.You're back in menu with Name,Source and Destination gaps which you filled. Touch ✓ again.

*I didn't try to tick ˝exclude from media scanning˝, you shouldn't too 'till you check if everything is working as it should. Try experimenting later.​

14.New pop-up will appear asking ˝Your source directory is not empty. Would you like me to move files to the destination(and overwrite existing files)?˝ Click NO again

15.You're in main menu in FolderMount, there's your game's name that you gave it earlier, next to it is grey pin. Touch that pin once and it will turn green.

* in FolderMount after every reboot a pin will turn grey. Just click it before trying to play game because it will not see .obb files and will try to download them again.​

16.Exit FolderMount and PLAY YOUR GAME!!! :D

EDIT:

There is a lot of devices, every of them has different internal and external SD paths, be sure to know them well. The best way to find this out is to go in FolderMount, try to create new bind, and by tapping Source and Destination gap see the path for each SD in the upper part of the screen.

Some SD card locations on various devices:

/mnt/sdcard0 - internal and /mnt/sdcard1 - external;

/mnt/sdcard - internal and /mnt/extSD - external

Also, if this guide helped you feel free to let me know that by pressing THANKS button :cool:
