A File represents an item in an ASPxFileManager control that is shown within the file container.
If the FileManagerSettingsFileList.View is set to Thumbnails, the file content includes a thumbnail and a name.
If the FileManagerSettingsFileList.View is set to Details, the file is a row in the details grid.
To customize the appearance style of files, use the FileManagerStyles.File property.
If the FileManagerSettings.AllowedFileExtensions property is specified, only files with extensions allowed by this property are displayed within the file container.
