that shows the size of the folder and files graphically? I read about it several months ago and forgot about it until now? I'm hoping it will help me find out why I keep getting "space low" alerts on my phone.
If you are getting low space alerts then you can just check the storage capacity in the menus > settings > storage. I would suggest clearing application caches to free up space, deleting unnecessary emails and text messages.
If you're sd card is low on space then view the files sizes of the data and delete anything you don't need or sync it to the cloud for future access.
