iPhones and iPads these days have quite a bit of storage, so you may have plenty of room to save documents on your device rather than spending money to upgrade your iCloud storage to the next tier. To do this you will want to set your internet downloads to automatically save locally, which is easy to do with Safari's new download manager and you will want to make sure you save email attachments locally. Also, anything you have stored in iCloud you can always move to a local folder in the Files app.
iCloud Drive makes it possible to share folders across Apple devices and between different users. Sharing a folder on the iPhone or iPad requires iOS 13 or later. iCloud Drive folders stored in the Files app on an iOS device can easily be shared with a few taps.
If you have ever received a zipped or compressed archive as an email attachment and tried to open it on your iPhone, you've seen that you can view the contents but can't edit the individual files, or share them individually. Surprisingly, as of iOS 12, there is no built in option to extract zipped files. You can, however, easily create a shortcut that will do it for you. Here's how to do it on iPhone and iPad:
The Files app was introduced in iOS 11 as a replacement to iCloud Drive app. It allows you to browse, search, and organize all your files stored on your device, in iCloud Drive or in other supported third-party apps, like Google Drive or Dropbox. You can organize your files by Name, Date or Tags, but first lets look at how to add third-party apps so all your files will be displayed.
One of the great features of iOS 11 and later is the Files app. Saving and browsing files directly on an iPhone, iPad or iPod touch now has native support. Not only can files be stored locally on the device, but iOS can take advantage of cloud-based storage solutions such as iCloud or Dropbox. Individual apps can even be configured to use different locations for file storage by default.
