If you want to save memory space on your Samsung Galaxy Tab, you can move apps to the SD card. Once you have installed the app to your Galaxy Tab, you can perform these steps.
Note: Apps that you move to the SD card cannot be accessed when the device is mounted to a computer.
1. From the home screen, press the Menu button below the screen.
2. Select Settings.
3. Tap Applications.
4. Tap Manage Applications.
5. Choose the app you wish to move.
6. Tap the Move to SD card button.
The Galaxy Tab will then go through the process of installing the app to the SD card. If you get a “Failed to move application” error, the app was probably included with the ROM of the device and cannot be moved.
Of course, this process can become tedious if you wish to move all of your apps to the SD card. Luckily there is an app called SDMove available in the Android Market that will do this for you. From SDMove you can simply tap Menu > Move All and all apps that can be moved will be.
If you ever decide you want an app to be moved back to the device memory, you can repeat steps 1-5 and choose Move to device.
