I want to create a folder that holds my correspondence, not a folder that hold an application, just my correspondence. I want to keep that folder on the screen where I can find it easily. It used to be available before with a right click. Now on iPhone 13, there is no right click. I think the right click was on Mac laptop.

Nope. Not easily.

iPhone does not directly support either path to this, either placing a folder from mail directly on the local storage or on the desktop, nor an automated way to extract arrived messages into local storage.

Your options here are to have one or more folders within mail for your correspondence as would be typical, or to manually extract each message from mail into the folder as you decide to archive the message.

I have many folders within mail, and those same folders on the server are available on both iPhone and Mac.

Apple does not provide a particularly easy way to get mail into and out of mail and into or out of a local or iCloud folder of files. Mail messages largely stay in mail.

You can automate some mail processing using iCloud mail rules with an iCloud email,account, but those iCloud rules are fairly limited in comparision to what Mac Mail app filtering rules allow. Shortcuts and the available amil-related triggers are also fairly limited here, too.

You could make a Shortcut to effectively get you to the correspondence folder, or to can add your own shortcut to the share sheet, but there’s no direct analog to the Mac desktop on iPhone. And what Shortcuts can do with mail and mail messages is limited, with no means to extract the current message to a file, which is central to what you are requesting.

In short… To do what you want here, you will want a Mac. Or it’s going to be manual. And clunky. iPhone expects mail to be kept in mail, not elsewhere in the file system.

Another consideration latent here is how this correspondence gets backed up. You’ll need to connect to and back up to a Mac, or store the correspondence on iCloud, or back up local storage to iCloud, as an iPhone can be lost or stolen or dunked, and that can mean the folder of correspondence on that iPhone is permanently unavailable. If the folder is stored in iCloud, you will still want backups, of course.

If you’d like to see this folder of correspondence scheme better supported and better automated, log feedback with Apple:

No. Folders on the home screen can only hold apps.

You can create folders for other types of files in the Files App as explained in the support document provided by BDAqua.

Files app > Browse tab > 3 dots menu at top right > New Folder.

The 3 lines on the upper right do not contain the choice of making a new folder.

I’m telling you this because you seem to think I had that choice.

You should see this on your phone.

Furthermore, you don’t need to buy more iCloud storage. You can use the On My iPhone location in the files app.

While this is clunky, you can save the content in emails by selecting Print in the share sheet (the arrow icon) and when the window opens up to print, pinch out on the letter and you can save it to the Files app as a pdf. You can select the new folder that you want to create as well for the location.

Let me see if I can get other help in here.
