Back up iOS saved games to your computer 

To transfer you saved games from one device to another you first need to back up the game files to you computer using DiskAid. Not all games can be backed up in this manner, but if you open the Apps "Documents" folder and find files inside, more often than not these files will be your saves. If you cannot see the game listed under the Apps section in the left navigation panel of DiskAid, or the folder structure does not look like it does in the following screen captures, you might need to select the "Display all Apps...", and "Show root path..." checkboxes in the Advanced Preferences

Firstly you need to locate the saved game files:

Once you have clicked "Copy to Computer", DiskAid will prompt you for the location that you wish to save these files. You can either navigate to the folder that you want and click "Save", or you can create a new folder specifically for the task

If you choose to create a new folder, you will be prompted to enter a name for it and then just click "Create"

Once you have clicked "Save", your files will begin to transfer to the location that you designated
