Just like iOS which introduced folders in iOS4, Android too allows users to create folders to store multiple items in it. Adding a folder is pretty easy but Android does not provide an easy option to rename the folder to something more rememberable.
Whenever you create or add a new folder to any Android home screen, the name remains "New folder" which is not very helpful when you add multiple folders to the same screen.
So how do you rename folders in Android? Well, it is actually pretty easy. When you add a "New folder" to a Android screen, open the folder and then long press (press and hold) the folder’s title bar where the name appears (initially "new folder"). When you do that, a dialog box "Rename folder" will appear, allowing you to enter a new name for the folder.
Enter the name of the folder in the dialog box and click on the "OK" button and your folder will be renamed. You can use the same steps to rename the folder to something else as well.
Just make sure to open the folder first so that it’s contents are visible. If you long press on the folder itself, you will be shown an option to remove it and not to change the folder name of the Android folder.
