How to Make Windows 10 Install Apps to an SD Card

When Microsoft released Windows 10 back on July 29th, an omitted feature was the ability to install apps to a MicroSD card, like you can on Windows Phone. Not having this ability out of the box was disappointing for owners of a Surface or other devices with low capacity SSD drives. One of the incentives of these devices is the ability to install an SD card to increase storage space.

Now with the recent release of the November update, version 1151 or Build 10586, that feature is available. Here’s how to find it and set it up.

Change Default App Install Location to an SD Card

To set this up, head to Settings > System > Storage. There you’ll see a list of your connected drives, including an installed SD card.

Settings Storage Windows 10

You can see what’s taking up space on each one by double clicking a drive.

Storage useage

While that’s a handy feature unto itself, here we want to set apps to save to the SD card. Under the Save locations section, change the New apps will save to menu to your SD card and then click Apply.

Change Apps Save Location

Depending on your local storage situation, you might also want to change the save locations for new docs, music, videos and photos, too.

This feature isn’t just for Microsoft Surface owners either, anyone running Windows 10 with the November update can set this up and choose options like a flash drive or external drive of any kind. For example, I installed a 256 GB SSD on my main production desktop and use this to install apps to a Western Digital external 2 TB USB 3.0 drive that’s always connected.

    Great idea,
    BUT – as for the File History and many other windows 10 facilities –
    You will need to ensure that:
    Firstly the device is always attached to your PC when the PC is running, (well the Application using the device)
    Secondly that that device and the partitions defined on it are always set to have the same letter assigned.

    You can (almost) permanently get windows to use the same letter each time by using Storage Management (Right click and select “Storage” from “My Computer”, then right-click on the partition within the device display.

    Windows records the letter you have specified within it’s own records, and also on the partition.
    That’s great until the device gets used on another PC and gets a new letter there, or there is already a device or partition using that letter when the device is plugged into the PC.

      Excellent points James. I assume most users would just plug in a 128 GB card and leave it.

        Yup,
        But it seems that the latest update may not complete if you have a card plugged in while doing the update.

        And there is the windows unilateral decision to permanently dismount all attached devices partitions ( and while MS and many others refer to using the device, windows actually needs a partition defined on the device and formatted with a file management system – FAT or NTFS).

        So – to avoid letter changes, you would need to have permanently connected devices for:
        your Applications
        File History
        and the attach use and detach – backup stores – wouldn’t want them attached or the malware could get at them at the same time it gets on your OS partition.

        External DVD on a laptop would also take a letter, and what happens if you are using a card in the single ‘slot’ for the apps and want to connect a different card – maybe a newer bigger faster one.

        Seems to me that MS are focussed on producing ‘marketing rabbits’ from the hat to distract from their problems with lack of cohesion in much of the act.

        Consider that almost all devices, and certainly all partitions have (hopefully unique) identity codes set on them so why not have these ‘facilities’ set to use file-storage partition identities rather than just the letter assigned when the device was last plugged into a system.
        (Way back in XP days you could set multi-boot selection to use a USB connected device by that id code using ‘Selection’ rather than it’s specific connection port.)

        However there has been a similar facility since DOS days –
        You could ‘attach’ a partition to be treated as if it’s contents were a folder of another partition.
        Rather than use a memory stick as speedboost – where there is a lot of writing done to the device, and thus reduced life, I used to copy folders of the installed apps to the stick, rename the original folder – create a new one with the original name and ‘attach’ the memory stick as that folders contents.

        That allowed apps and the system to update the contents, while redirecting substantial amounts of I/O from the drive containing the main OS files and the memory paging location.
        BUT – it did require the partition to be the same at every boot, or require the ‘attachment to be redone – such as when you upgraded the main drive and created another partition on it.
        A situation I admit I have not checked with this latest wabbit from MS.

    Very handy and usefull! I don’t own a device that I want to use this one, but I’m sure for the future it is a very handy feature. Hopefully Google will notice this, so it can do the same on Android. 😉

    Hi Brian! I recently bought an HP Stream 11 and I just installed a micro SD Card. Would it matter if my microSD card is in exFAT format? Or should I be reformatting it first to NTFS format?
