# Viewing and Editing Files

You can view files directly in the CTERA Drive Mobile app. Unless the file has already been downloaded, the file is downloaded and then opened. Files that were previously downloaded and still in the cache, or that were made available offline are opened immediately.

**To view a file:**

1. Navigate to the file you want to open.
2. Tap the file to download and view the file in the online viewer.
          **Note**

          

Even if the file cannot be viewed, for example, a zip file, it is still downloaded.

### iOS Only: Viewing and Editing Files in iOS Files App

You can add the CTERA Drive Mobile app as a location in the iOS Files app. The folders in your Cloud Drive and in the Shared With Me cloud folder are then available in the iOS Files app. In the iOS Files app you can view and edit the files using any of the options available for that file in the iOS Files app. For example, you can create a duplicate of a file, share a file, rename or markup a file. Edited files are uploaded to the CTERA Portal.

When first tapping a file in the iOS Files app, the file is downloaded and then opened. Even if the file has been downloaded in the CTERA Drive Mobile app, it is still downloaded to the iOS Files app. Files that were previously downloaded in the iOS Files app and are still in the cache are opened immediately.

**To manage a folder or file:**

1. Add CTERA Portal to the available locations in the iOS Files app.
2. Navigate to a file in the CTERA Portal.
3. Do one of the following:

          **Note**

          

Even if the file cannot be viewed, for example, a zip file, it is still downloaded.
  - Long press the folder or file for the available options and choose the required option.
  - Tap the folder to navigate through the folder tree.
  - Tap the file to download and view the file. After the file is downloaded, the icon changes to a thumbnail.

Any changes made to folders and files in the iOS Files app are synced to the CTERA Portal.

          **Note**

          

The options displayed depend on what is enabled for the chosen folder or file.

Or, alternate options are displayed.
