# Access file fields

You can use the `Sitecore.Data.Fields.FileField` class to access data template fields of type `File`. You can use the `Sitecore.Data.Fields.FileField.MediaItem` property to access the media item selected in the field. For example, to access the media item referenced by the *File* field named `FileField` in the */Sitecore/Content/Home* item in the *Master* database:

```csharp
Sitecore.Data.Database master = Sitecore.Configuration.Factory.GetDatabase("master");

Sitecore.Data.Items.Item home = master.GetItem("/sitecore/content/home");

Sitecore.Data.Fields.FileField fileField = home.Fields["filefield"];

Sitecore.Data.Items.Item file = fileField.MediaItem;

if (fileField==null) {
    // File field not found
}

else if (file==null) {
    // No file selected
}
else {
    Sitecore.Data.Items.MediaItem media = new Sitecore.Data.Items.MediaItem(file);
    // Process media item
}

```

You can update the value of a *File* field by updating the `Sitecore.Data.Fields.FileField.MediaID` and `Sitecore.Data.Fields.FileField.Src` attributes. For example, to ensure the *File* field named *FileField* in the */Sitecore/Content/Home* item in the *Master* database specifies the */Sitecore/Media Library/Files/Sample* media item:

```csharp
Sitecore.Data.Database master = Sitecore.Configuration.Factory.GetDatabase("master");

Sitecore.Data.Items.Item home = master.GetItem("/sitecore/content/home");

Sitecore.Data.Fields.FileField fileField = home.Fields["filefield"];

Sitecore.Data.Items.Item sample = master.GetItem("/sitecore/media library/files/sample");

if (fileField == null ){
    // File field does not exist
}

else if (sample == null) {
    // File does not exist
}

else if (fileField.MediaID != sample.ID) {

    home.Editing.BeginEdit();

    fileField.MediaID = sample.ID;
    fileField.Src = Sitecore.Resources.Media.MediaManager.GetMediaUrl(sample);

    home.Editing.EndEdit();

}

```
