Adopting your SD card as internal storage will install new apps to your SD card by default if the app developer allows it. You can move the app back to internal storage later if you want. Additionally, when you adopt your SD card as internal storage, you cannot remove the SD card from the device without affecting the functionality of your device and the SD card is not usable in any other device, including your PC.
Once you adopt an SD card on a Marshmallow device, it will only work with that device. You can read more about the difference between portable and internal storage on an Android device. Be sure to back up the data on your SD card to your computer before adopting your SD card as internal storage. The adoption process will erase all data on the SD card. You cannot remove the SD card from the device and plug it in directly to your PC to transfer files.
If the SD card is a less expensive, slower SD card, it will slow down your apps and device. Insert the SD card in your device. You should see a notification saying that a new SD card was detected. A screen displays allowing you to choose whether you want to set up the SD card as portable storage or internal storage. A message displays warning you that after the SD card is formatted as internal storage, it will only work in that device.
You are also advised to back up the data on the card. If there are still apps installed on the SD card that you forgot to move back to the internal storage, the device displays a warning that the apps will be erased.
This step will move your photos, files, and some apps to the SD card. This selects the SD card as the preferred storage location for all apps, databases, and data. The internal storage remains the preferred storage for all content. When the process is finished, a message displays telling you that your SD card is working.
Tapping on one of the items under Device storage on the Storage screen in the Settings app allows you to view usage information about that storage location. You can manually move apps between internal storage and the SD card, but this is not recommended, and can cause unintended consequences on some devices. You do not need to specify where to store content for each app. By default, apps will always store their content in the preferred storage location.
If you only want to store pictures, movies, and music on your SD card, using the SD card as portable storage is a better option for you. In addition, this option is only available for some apps—the app developer must deem them movable in order for them to be moved.
So depending on the apps you want to move, this may or may not be very useful to you. On a stock Android device, such as the Nexus 7, swipe down once to access the Notifications panel, and again to access the Quick Settings panel. Scroll through the list of apps and tap the app you want to move to the SD card. You can scroll through your own list of apps and choose to move an app that is taking up a significant amount of space on your device.
Tap the button to begin moving it. There is a better way to get an overall view of which apps can and cannot be moved to the SD card. There is also a paid version , but the free version is good enough for this purpose. Next, follow the steps below to the letter, and you should have some extra space on your SD card for apps. Before partitioning your SD card, be sure to back up all data on your SD card.
This partitioning procedure will erase everything on it. Once your data is backed up, leave the SD card in your PC for the partitioning process. The following screen displays. Select the disk for your SD drive. This is the point at which all the data on the SD card will be erased. The first partition will be used for data.
Creating partitions on an SD card so you can install apps to it on an Android device is different from partitioning a drive for a PC. Next, you need to define the type of file system for the data partition. By default, the size of this partition is the available size of the SD card. Click and hold on the yellow border and drag it to the left until you get the approximate size you want for your data.
The remaining space on the SD card is listed as unallocated below the data partition you just created. Now, you need to define the second partition for the apps. Windows can only recognize the first partition on a removable disk. However, since we are not using this SD card on a Windows PC, we can continue to create the second partition. The remaining space on the SD card is automatically used for the second partition.
However, the changes are not final yet. A confirmation dialog box displays making sure you want to apply the changes. Now that you have a properly partitioned SD card, insert it back into your Android device and boot up the device. There is a paid version of the app, but the free version will suffice for this procedure. That should reset the app. Once your device has rebooted, open Link2SD again. You should not see any dialog box display. Instead, you should see a list of apps and some options on the top of the app screen.
If you want to automatically install new apps to the SD card rather than the internal storage, we recommend doing that now. To do this, tap the menu button three vertical dots in the upper-right corner of the screen. Make sure the first three check boxes are all selected. So, data files for apps installed on the SD card will still be stored on the internal storage. Use the back arrows at the top of each screen in Link2SD to go back to the previous screen.
You can also use the back button on your device. Any files you transferred from your PC to the SD card are on that partition. Word is also taking up a total of MB of space on the internal storage. However, we can get beyond that limitation. We open Link2SD and scroll in the list of apps until we get to Word and tap on it.
Notice the white box being called out on the image below. That indicates how much space is being used by the app on the internal storage. The orange box below that shows the amount of space the app is using on the SD card. We want to move as much as we can of that MB to the SD card as possible. It just seems to be there as a convenience for apps that can normally be moved to the SD card, so you can use Link2SD as a general app manager. Leave the first three file types selected.
Notice that To illustrate an app being installed directly to the SD card, I installed a simple Notepad app from the Play Store and it was installed on the SD card, bypassing the internal storage, as shown below.
If you remove the device, any apps you moved to the SD card will not be usable without the SD card. You can either do it using the phone itself or a third party app manager.
There are many apps that manage other apps. Some are free while others are premium. Do some research and decide which app manager you like the look of and has been well reviewed. The aptly named App Manager and File Manager are two popular choices that have received quality reviews. Some third party app managers are free while others are premium, do some research and decide which app manager you like the look of.
Work through your apps and move them around as you see fit. If you want to install apps directly onto your SD card by default, you can do that too. You will need to install the Android SDK, which is a small program that allows your PC to communicate with the Android operating system. It is safe to download and install from the link provided below. This PC process sets your SD card as the default install location for apps going forward. You should now be able to install most apps directly onto the SD card.
However, not every app will work correctly using this method.
