For those of us who love our apps, or have limited storage on our phones, freeing up space can be a concern. Prior to the Windows Phone 8.1 update, we were limited to installing apps directly on the phone, so when things got tight, one might take to uninstalling rarely-used apps to free up precious space. And anyone who has had to uninstall a bunch of apps at once can tell you how much of a hassle it can be to go through the list one by one to clear them out.
However, in this new post-8.1 era, we now have the ability to conserve device storage by installing apps directly to a micro SD card, should our device have one. With Storage Sense, it becomes easy to move apps that are already installed on your phone over to micro SD in a group, rather than individually. Similarly, if you want to uninstall several apps at once, you can use Storage Sense to do that as well.
