You can change your Firebase Security Rules for Cloud Storage to [allow unauthenticated access for specific situations](/docs/storage/security/rules-conditions#public). However, for most situations, we strongly recommend [restricting access and setting up robust security rules](/docs/storage/security/get-started) (especially for production apps). Note that if you use Google App Engine and have a default Cloud Storage bucket with a name format of `*.appspot.com`, you may need to consider [how your security rules impact access to App Engine files](/docs/storage/gcp-integration#security-rules-and-app-engine-files).\n\nDelete a File\n\nTo delete a file, first\n[create a reference](/docs/storage/unity/create-reference)\nto that file. Then call the `DeleteAsync()` method on that reference. \n\n```c#\n// Create a reference to the file to delete.\nStorageReference desertRef = storageRef.Child(\"images/desert.jpg\");\n\n// Delete the file\ndesertRef.DeleteAsync().ContinueWithOnMainThread(task =\u003e {\n if (task.IsCompleted) {\n Debug.Log(\"File deleted successfully.\");\n }\n else {\n // Uh-oh, an error occurred!\n }\n});\n```\n| **Note:** Deleted files are typically recoverable for 7 days with [soft delete](https://cloud.google.com/storage/docs/soft-delete), which is enabled by default.\n\nHandle Errors\n\nThere are a number of reasons why errors may occur on file deletes,\nincluding the file not existing, or the user not having permission\nto delete the specified file. More information on errors can be found in the\n[Handle Errors](/docs/storage/unity/handle-errors)\nsection of the docs."]]
