Files can be located using a durable and universal file identifier. A content URI includes a file protocol URI specifying a path to a file. The file protocol URI includes a query string specifying properties of the file that can be utilized to locate the file, such as an object ID property specifying a GUID for the file and a volume ID property specifying a GUID for a storage volume storing the file. The content URI can be utilized to locate the file using the file protocol URI and its associated query string even if the file has been moved, renamed, or is accessed on a different computing device. Operations can then be performed using the file, such as resuming a previously performed activity that used the file. 可以使用持久且通用的文件标识符定位文件。内容URI包括指定到文件路径的文件协议URI。文件协议URI包括指定可用于定位文件的文件的属性的查询字符串，诸如指定文件的GUID的对象ID属性和指定存储文件的存储卷的GUID的卷ID属性。即使文件已被移动、重命名或在不同的计算设备上被访问，也可以利用内容URI来使用文件协议URI及其相关的查询字符串来来定位文件。然后可以使用该文件执行操作，诸如恢复使用该文件的先前执行的活动。
