Google Apps: Moving Google File to Google Folder

You can move a Google File to a Google Folder two ways!

In Google Drive tap files in the bottom right corner.
You can organize the files by name, or the other options shown. It may be easiest to find things by last modified. You can also search if you’d like.
Find the document you would like to move and tap on it to select it.
You can drag it to the folder like shown OR you can tap on the folder with the arrow icon at the top and move it that way
If you choose the second way you will see this screen. Tap on my drive. Select the folder you want to move it to. Tap move here.
