One of the more popular system apps that Nokia makes for its Lumia line would be Storage Check, a tool that allows the device’s memory to be broken down to see where everything is going. But besides just g a pretty graph of storage layout, users can delete Temporary files and manage maps (including moving them to a SD card).
Version 18.104.22.168 is now live in the Nokia Collection and while it probably won’t do anything for most users today, it may squash some bugs (the changlog was last updated for version 1.2.2, which mentions new device support, probably for the Lumia 625).
Regardless, users can now go an update their Storage Check app by heading to the Store or by grabbing the link here. Thanks, Akash P., for the tip!
