Looks like this would be caused by the fact that there is a System\ModelsFile class in the same namespace (see https://stackoverflow.com/a/17747378/6652884) but I have no idea why it would only just now become an issue for you.
What build of October were you previously running?
What is your server environment like? i.e. what server software are you using?

Also, could you check if this also affects Mail Layout, Mail Partials, and Mail Brand Settings?

[alvaro-canepa]

This affect Mail Layout, Mail Partials, and Mail Brand Settings too. And the same issue affect to MediaManager, but with Form class instead of File.

I have another OC (same server) with build 424 and I can access to Mail Templates, but if I send an email, I have this exception.

The server is an Ubuntu Linux 15.10
Apache 2.4.23
PHP 7.0.9

The environment is development, this installation is for devel and test plugins and themes.

The MediaManager issue would be the same thing as this because it's been moved to Backend\Widgets, which already had a Backend\WidgetsForm class. I'll need to discuss this with @daftspunk, the solution is probably to use those aliases under another name:

use Form as FormAlias;
use File as FileAlias;

and then update the references in the files that use those aliases to call methods on FormAlias instead of Form.

[alvaro-canepa]

Great, this simple solution works fine. I tested without problems.
