iOS: When you receive an email attachment on iOS, chances are you need to sort it out in another app. To make life easier for yourself, OS X Daily notes that saving this attachment to iCloud Drive makes the process a little smoother.
In the Mail app, all you have to do is press and hold the attachment, tap the Save Attachment option, and then select the iCloud Drive folder where you want to save it. Now you can easily open it in another app, edit it and really know where the hell it is stored so you can easily access it later.
