本申请要求在2020年07月07日提交中国国家知识产权局、申请号为202010648535.5、申请名称为“一种打开文件的方法及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种打开文件的方法及设备。
背景技术
随着智能终端的发展，一个用户拥有多个智能终端的场景越来越多，例如智能手机、平板电脑(PAD)、或个人计算机(PC)等设备。多设备之间的互联互通给用户带来了较好的体验。
目前，为了提高用户的体验，提供了多屏协同功能(或者，称为多设备协同功能)。在多屏协同功能下，一个设备上的文件可以在另一个设备上打开。例如手机和PC进行多屏协同，则在PC的显示屏上会显示手机的显示界面，在PC上显示的手机的显示界面也可理解为投屏界面。用户在PC的投屏界面上操作，例如用户选择打开文件A，则PC可以打开文件A。或者，用户在手机上操作，例如用户选择打开文件B，同样的，PC可以打开文件B，而手机上并不会打开文件B。PC相对于手机来说显示屏的面积更大，用户在PC上观看该文件，可以提升用户的观看效果。
可以看到，在多屏协同场景下，无论用户在参与多屏协同的哪个设备上操作，结果都是在其中一个设备上进行响应。例如在手机和PC进行多屏协同时，用户无论在手机还是在PC上操作以打开一个文件，结果都是在PC上打开该文件，在手机上不会打开。但如果用户实际是希望在手机上观看，按照目前的方式是无法实现的，用户只能退出多屏协同模式，才能正常在手机上打开并观看相应内容，而这个过程需要多个步骤的操作，较为繁琐。

本申请还提供一种多屏协同***，该多屏协同***可包括第一设备和第二设备。当然，该多屏协同***还可以包括其他设备，例如三个或三个以上的设备也可以进行多屏协同。本申请实施例主要以两个设备之间的多屏协同过程为例。
目前，在多屏协同(或者，称为多设备协同)场景下，无论用户在参与多屏协同的哪个设备上操作，结果都是在其中一个设备上进行响应。例如在手机和PC进行多屏协同时，用户无论在手机还是在PC上操作以打开一个文件，结果都是在PC上打开该文件，在手机上不会打开。但如果用户实际是希望在手机上观看，按照目前的方式是无法实现的，用户只能退出多屏协同模式，才能正常在手机上打开并观看相应内容，而这个过程需要多个步骤的操作，较为繁琐。
例如，一个用户使用手机操作，对于手机中的某个文件，需要在个人计算机(personal computer，PC)上打开文件，以供使用PC的用户观看，这样就不必两个用户同时观看手 机，PC的显示屏较大，也能带来较好的观看效果。在这种情况下，手机和PC就可以进入多屏协同模式，手机可在多屏协同模式下打开文件，该文件就会显示在PC上。可参考图2，为在多屏协同模式下打开文件的过程的示意图。
图2中的1，表示用户点击手机显示屏上显示的文件，手机上安装的手机助手(或者，称为手机PC助手)获得用户的点击操作信息，并进行点击响应。或者，图2中的1，表示用户点击PC的显示屏上的手机的投屏界面中显示的文件，PC上安装的PC管家获得用户的点击操作信息，并进行点击响应。
图2中的2，表示PC上安装的PC管家将获得的用户的点击操作信息发送给手机助手。
图2中的3，表示手机将进行文件打开截断处理。这是因为，如果按照正常的流程，手机确定用户进行了用于打开手机上的文件的操作，则手机会响应该操作，并打开相应的文件。但在多屏协同模式下，只能由PC来打开该文件，手机端不会打开，因此手机需要对原本需要进行的打开该文件的操作进行截断。
图2中的4，表示手机获取该文件的路径。这里所述的该文件的路径，是指该文件的绝对路径，即，该文件在手机中的存储路径。
图2中的5，表示手机助手将在手机中的分布式文件管理***(ming distributed file system，MDFS)中创建软链接，该软链接指向一个存储路径，该存储路径为该文件在手机中的存储路径，例如该文件在手机的安全数码卡(secure digital memory card，SD)中的存储路径或该文件的统一资源定位符(uniform resource locator，URL)等。另外，该软链接还与该文件的元数据相关联，该文件的元数据例如包括该文件的存储路径，当然还可能包括该文件的其他内容，例如该文件的类型信息等。
图2中的6，表示手机端的分布式文件管理***将该文件的元数据同步到PC端的分布式文件管理***。
图2中的7，表示手机助手获得分布式文件管理***中创建的软链接的路径。
图2中的8，表示手机助手将手机端的分布式文件管理***中创建的软链接的路径发送给PC管家。另外，手机助手也能够获得该文件的元数据，例如该文件的类型信息等，手机助手也可以将获得的该文件的元数据发送给PC管家。
图2中的9和10，表示PC管家根据该文件的类型信息等，调用能够打开该文件的应用，另外，PC管家也将软链接的路径发给该应用。图2以该应用是Microsoft office应用为例，在图2中表示为“办公应用”。
图2中的11，表示office应用根据该软链接的路径，打开该软链接。
图2中的12，表示PC端的分布式文件管理***根据该软链接对应的元数据(例如根据元数据所包括的该文件的存储路径)，到手机端的分布式文件管理***中请求获得该文件。
图2中的13，表示手机端的分布式文件管理***读取该软链接实际指向的文件。另外，手机端的分布式文件管理***将读取的文件发送给PC端的分布式文件管理***，从而PC端的office应用能够打开该文件。
根据如上流程可以看到，目前在多屏协同(或者，称为多设备协同)场景下，无论用户在参与多屏协同的哪个设备上操作，结果都是在其中一个设备上进行响应。例如在手机和PC进行多屏协同时，用户无论在手机还是在PC上操作以打开一个文件，结果都是在PC上打开该文件，在手机上不会打开。但如果用户实际是希望在手机上观看，按照目前的 方式是无法实现的，用户只能退出多屏协同模式，才能正常在手机上打开并观看相应内容，而这个过程需要多个步骤的操作，较为繁琐。
鉴于此，在本申请中，设备可以根据用户的操作确定用户的操作焦点，或者说确定用户究竟希望在哪个设备上观看，从而根据用户的意图来选择相应的设备进行响应。通过这种方式，能够使得响应结果符合用户的需求，提高用户的使用体验。例如在手机和PC进行多屏协同时，用户如果在手机上操作以打开一个文件，则该文件可以在手机上打开，或者用户如果在PC上操作以打开一个文件，该文件可以在PC端打开，可见，用户无需退出多屏协同模式也能在手机上打开并观看相应内容，简化了用户的操作过程，设备也无需响应多次，有助于节省设备的功耗。

在本申请实施例中，第一设备和第二设备要进行多屏协同。为了便于理解，在下文的介绍过程中，以第一设备是手机、第二设备是便携计算机为例，手机的结构例如为图1所示的结构，在此意义上来说，图1所示的电子设备100，也可以称为手机100。另外，第一设备要实现多屏协同功能，例如可通过第一设备内安装的第一管家软件来实现，第二设备要实现多屏协同，可通过第二设备内安装的第二管家软件来实现。根据前文的介绍可知，第一管家软件可以是在第一设备中单独运行的软件模块，或者也可以是第一设备的***软件的一部分。第二管家软件可以是在第二设备中单独运行的软件模块，或者也可以是第二设备的***软件的一部分。另外，“投屏软件”也可以有其他名称，例如也可以称为“投屏应用(APP)”等。其中，第一设备如果是手机100，那么第一管家软件也可以称为手机助手等。应理解：管家软件也可以称作其他名称，“管家”这个词本身没有特定含义，并不是说管家软件一定要管理该管家软件所在的设备内的其他软件。
另外，在本申请实施例中，软件模块与应用(APP)可以是同种概念，例如手机助手是软件模块，也是应用，因此，“软件”，也可以替换为“应用(APP)”，例如“管家软件”也可以称为“管家应用”，还有“投屏软件”，也可以称为“投屏应用”。或者，应用可以包括一个或多个软件模块，但不能认为软件模块本身就是应用。例如，管家软件是一个软件模块，但不是独立的应用，可认为管家软件是设置在相应的应用(例如管家应用)中的软件模块，或者也可以是设置在***软件中的软件模块；同理，投屏软件是一个软件模块，但不是独立的应用，可认为投屏软件是设置在相应的应用(例如投屏应用)中的软件模块，或者也可以是设置在***软件中的软件模块。其中，“应用”，是指用户可以直观调用的，例如在手机的显示界面上显示的“短信”、“应用市场”等图标，都代表相应的应用。在下文的介绍过程中，以软件模块与应用是同种概念为例。
图3A示出了手机100的一GUI，该GUI为手机的桌面201。用户希望手机100和便携计算机进行多屏协同，则用户需要使手机100和便携计算机都进入多屏协同模式。要使得手机100和便携计算机进入多屏协同模式，可以通过预设方式，预设方式可以包括多种操作方式。例如参考图3B，用户可手持手机100碰一碰便携计算机，例如碰一碰便携计算机的NFC区域，则手机100和便携计算机可建立NFC连接，且手机100和便携计算机均进入多屏协同模式，则预设方式就是“碰一碰”的方式。即，用户只需进行一个操作(碰一碰操作)，就既能在两个设备之间建立连接，又能使得两个设备进入多屏协同模式。其中，图3B主要是示意手机100和便携计算机碰一碰的过程，因此并未详细画出手机100的显示界面。
或者，用户可开启手机100和便携计算机的蓝牙功能，例如手机100在开启蓝牙功能后会扫描周围的蓝牙设备，如果扫描到便携计算机，则手机100和便携计算机可建立蓝牙连接，且手机100和便携计算机均进入多屏协同模式，则预设方式就是用户开启蓝牙功能的方式，或者是手机100扫描便携计算机的方式。即，用户只需进行一个操作(开启蓝牙功能的操作)，就既能在两个设备之间建立连接，又能使得两个设备进入多屏协同模式。或者，用户开启手机100和便携计算机的蓝牙功能，例如手机100在开启蓝牙功能后会扫描周围的蓝牙设备，如果扫描到便携计算机，则手机100和便携计算机可建立蓝牙连接。在手机100和便携计算机建立蓝牙连接后，用户再进行相应操作，使得手机100和便携计算机进入多屏协同模式。例如便携计算机安装了第二投屏软件，手机100安装了第一投屏软件，用户所进行的操作，例如为使用第一投屏软件扫描第二投屏软件提供的二维码的操作，而用户进行该操作，就视为预设方式。即，用户需要进行至少两个操作，分别使得两个设备建立连接以及进入多屏协同模式。
或者，手机100和便携计算机也可以通过Wi-Fi或其他方式建立连接，并进入多屏协同模式。
或者，便携计算机安装了第二投屏软件，手机100安装了第一投屏软件，第一投屏软件和第二投屏软件可以是两种不同投屏软件，或者也可以是同一种投屏软件，只是安装在不同的设备上。根据前文的介绍可知，第一投屏软件可以是在手机100中单独运行的软件模块，或者也可以是手机100的***软件的一部分。第二投屏软件可以是在便携计算机中单独运行的软件模块，或者也可以是便携计算机的***软件的一部分。应理解的是，“投屏软件”也可以有其他名称，例如可以称为“投屏应用”等。另外，投屏软件和管家软件可以是同一软件模块，例如，第一投屏软件和第一管家软件可以是同一软件模块，第二投屏软件和第二管家软件可以是同一软件模块；或者，投屏软件和管家软件可以是不同的软件模块，例如，第一投屏软件和第一管家软件可以是不同的软件模块，第二投屏软件和第二管家软件可以是不同的软件模块。例如，第一投屏软件是手机100的***软件的一部分，而第一管家软件是在手机100中单独运行的软件模块，不属于***软件，则认为第一投屏软件和第一管家软件是不同的软件模块；又例如，第一投屏软件和第一管家软件都是在手机100中单独运行的软件模块，但二者是不同的软件模块，也认为第一投屏软件和第一管家软件是不同的软件模块，等等。用户可在便携计算机上打开第二投屏软件，以及在手机100上也打开第一投屏软件，便携计算机上的第二投屏软件可以提供二维码，用户可以用手机100通过手机100上的第一投屏软件扫描便携计算机的第二投屏软件提供的二维码，从而手机100和便携计算机可以建立连接以及均进入多屏协同模式，或者，用户通过手机100上的第一投屏软件扫描便携计算机的第二投屏软件提供的二维码的操作只用于两个设备进入多屏协同模式，而这两个设备在此之前已建立了连接，例如建立了蓝牙连接或Wi-Fi连接等。
或者，用户可以在便携计算机的第二投屏软件和手机100的第一投屏软件上登录同一账户，例如在便携计算机的第二投屏软件和手机100的第一投屏软件上输入相同的账号和密码，这样无需扫描二维码也能使得手机100和便携计算机可以建立连接以及进入多屏协同模式，则预设方式就是用户在便携计算机的第二投屏软件和手机100的第一投屏软件上输入相同的账号和密码的操作的方式。或者，用户在便携计算机的第二投屏软件和手机100的第一投屏软件上输入相同的账号和密码的操作只用于两个设备进入多屏协同模式，而这 两个设备在此之前已建立了连接，例如建立了蓝牙连接或Wi-Fi连接等。
其中，如果手机100安装了第一投屏软件，则第一管家软件能够捕捉用户针对第一投屏软件所进行的操作，以及第一管家软件能够将来自便携计算机(或者说，来自第二管家软件)的指令发送给第一投屏软件；同理，如果便携计算机安装了第二投屏软件，则第二管家软件能够捕捉用户针对第二投屏软件所进行的操作，以及第二管家软件能够将来自手机100(或者说，来自第一管家软件)的指令发送给第二投屏软件。
或者，用户还可以通过其他方式使得手机100和便携计算机均进入多屏协同模式，具体方式不做限制。
另外可参考图3C，在进入多屏协同模式后，便携计算机的显示屏上会显示手机100的当前的显示界面202，该显示界面202也可以称为投屏界面202或者录屏界面202，投屏界面202是手机100的显示界面的镜像，在便携计算机上显示的投屏界面202与手机100的显示界面是同源的，即，都源于手机100。例如，手机100将手机的显示界面的信息发送给便携计算机，从而便携计算机可按照与手机100的显示屏相同大小的比例显示该投屏界面202。在便携计算机显示投屏界面202后，用户也可以对投屏界面202进行放大或缩小等操作，以改变投屏界面202的面积，或者用户还可以对投屏界面202进行拖拽等操作，以改变投屏界面202在便携计算机的显示屏上的位置。
在手机100和便携计算机均进入多屏协同模式后，按照本申请提供的技术方案，用户可以选择在便携计算机侧观看手机上的内容，便携计算机的显示屏的尺寸较大，通过大屏观看能够为用户带来较好的观看体验；或者，用户也可以选择在手机侧观看手机上的内容，手机更便于携带，可满足用户随时观看的需求。下面介绍如何实现选择设备进行观看。
例如，用户在便携计算机上显示的投屏界面202上进行了第一操作，第一操作例如为触摸操作，可参考图4A，第一操作为用户用手指触摸投屏界面202上的“文件3”这一文件图标的操作，这表示用户想要打开文件3。便携计算机的显示屏上的触摸传感器可采集(或，捕捉)第一操作的事件信息，或者说，便携计算机的显示屏上的触摸传感器可捕捉用户的第一操作，并获得第一操作对应的事件信息，该事件信息可指示第一操作。因为第一操作所针对的区域是投屏界面202，因此触摸传感器可将采集的第一操作的事件信息发送给第二管家软件。第一操作的事件信息例如包括便携计算机的标识，可选的，还可以包括第一操作的位置信息等。第一操作的位置信息例如为第一操作在投屏界面202内的相对位置信息，这样，即使投屏界面202在便携计算机的显示屏上的位置不同，而第一操作的相对位置信息是不变的。对于手机100来说，根据手机100的显示屏194与投屏界面202的面积转换比例，以及第一操作的相对位置信息，就可以确定第一操作所对应的文件。
或者，第一操作也可以是声控操作、手势操作、或在便携计算机的显示屏上进行按压的操作等其他操作，则便携计算机内采集第一操作的传感器也会有所不同。本申请实施例对于第一操作的类型不做限制。
第二管家软件将第一操作的事件信息发送给第一管家软件，发送方式取决于手机100和便携计算机之间的连接方式，例如NFC或蓝牙或Wi-Fi或移动网络等。第一管家软件接收第一操作的事件信息后，由于第一操作的事件信息包括便携计算机的标识，因此第一管家软件确定第一操作的事件信息对应于便携计算机，即，确定第一操作是在便携计算机上进行的操作，或者说，确定第一操作对应的文件图标(例如，“文件3”这一文件图标)位于便携计算机的显示界面上。那么，第一管家软件可以确定第一操作对应的文件的存储路 径，例如，第一操作的事件信息包括第一操作在投屏界面202内的相对位置信息，则第一管家软件根据投屏界面202和手机100的显示屏194之间的面积转换比例，以及第一操作的相对位置信息，可以确定第一操作所对应的文件，例如文件3，从而第一管家软件可以确定文件3的存储路径。第一管家软件可以在手机100的分布式文件管理***中创建该文件对应的软链接，该软链接指向该文件的存储路径，例如该软链接指向该文件在手机的SD卡中的存储路径或该文件的URL等。另外，该软链接还与该文件的元数据相关联。手机100端的分布式文件管理***可以将第一操作所对应的文件的元数据同步到便携计算机端的分布式文件管理***。
一个文件的元数据，也可以称为该文件的描述信息等，一个文件的元数据例如包括该文件的存储路径，除此之外，可选的，还可以包括如下的一项或多项：该文件的名称，该文件的类型信息，或，该文件的大小信息。例如，一个文件的元数据可包括该文件的存储路径信息；或者，一个文件的元数据可包括该文件的类型信息和该文件的存储路径信息；或者，一个文件的元数据可包括该文件的大小信息、该文件的名称和该文件的存储路径信息，等等。一个文件的存储路径信息所指示的存储路径，可以是指该文件在手机100中的存储路径。在如上的示例中，第一操作对应的文件为文件3，则手机100端的分布式文件管理***可将文件3的元数据同步到便携计算机端的分布式文件管理***。
第一管家软件可获得手机100端的分布式文件管理***中创建的软链接的路径，第一管家软件可将该软链接的路径发送给第二管家软件。另外，第一管家软件也能够获得该文件的元数据，例如该文件的类型信息等，第一管家软件也可以将获得的该文件的元数据发送给第二管家软件。
第二管家软件根据该文件的类型信息等，确定并调用能够打开该文件的应用，例如第二管家软件确定第二应用能够打开该文件。在本申请实施例中，如果“软件”和“应用”这两个名词可互换，则“第二应用”也可以称为“第二软件”；或者，如果“软件”和“应用”不是同一层级的概念，不能互换，则可认为第二应用内设置了一个或多个软件模块。例如，文件3的类型信息指示文件3的类型为图像类型，则第二管家软件可确定图像应用能够打开文件3；又例如，文件3的类型信息指示文件3的类型为Microsoft Word文档，则第二管家软件可确定Microsoft office word应用能够打开文件3。另外，第二管家软件也将该软链接的路径发送给第二应用。
第二应用根据该软链接的路径，打开该软链接。则，便携计算机端的分布式文件管理***可以根据该软链接对应的元数据，从手机100中获取文件3，对此可以理解为，从手机100中获取文件3的数据。例如，便携计算机端的分布式文件管理***可以根据该软链接对应的元数据所包括的文件3的存储路径信息，从手机100中获取文件3。从而，第二应用就能够打开文件3。
可参考图4B，为便携计算机上打开了文件3的示意图，图4B中的界面203即表示便携计算机上打开的文件3的界面，图4B以文件3是word文件为例。在便携计算机上打开文件后，用户可调整界面203的大小，如图4B中界面203和投屏界面202可一起显示。或者，界面203也可以覆盖投屏界面202，如图4C所示。或者，用户可以将投屏界面202设置为“始终显示在最顶层”，则投屏界面202的部分区域或全部区域也可能位于界面203内，如图4D所示。
在这种方式下，在便携计算机上打开了文件3，则在手机100上不会打开文件3。
另外，便携计算机还可将文件3的数据存储在便携计算机中，例如便携计算机可通过第二应用可将文件3的数据存储在便携计算机的本地文件***中，例如可作为临时文件来存储。
用户可在便携计算机上通过第二应用观看文件3，用户也可以在便携计算机上通过第二应用对文件3进行编辑操作，例如可在文件3中删除内容、增加内容或修改内容等。用户在对文件3操作完毕后，可以保存文件3，则便携计算机可以更新存储的文件3的数据，得到文件3的更新数据。文件3的更新数据可以理解为是更新后的文件3，相当于，便携计算机是用文件3的更新数据覆盖了便携计算机存储的文件3的原数据。便携计算机可以将文件3的更新数据发送给手机100，例如，便携计算机可通过便携计算机的分布式文件管理***将第二文件同步给手机100的分布式文件管理***，则手机100可以用文件3的更新数据覆盖手机100的本地文件***所存储的文件3的原数据，这样就实现了文件3的更新。其中，便携计算机可以在用户每次更新文件3后都将文件3的更新数据发送给手机100，以使得文件3在手机侧能够得到及时更新；或者，便携计算机也可以在用户关闭文件3后再将文件3的更新数据发送给手机100，以减少发送更新数据的次数，节省传输开销。另外，便携计算机在将文件3的更新数据发送给手机100后，便携计算机可以删除存储的文件3的更新数据，例如可删除该临时文件，以释放存储空间。
如上介绍的是在进入多屏协同模式后，用户在便携计算机上进行操作的过程。或者，在进入多屏协同模式后，用户也可能会继续在手机100上进行操作。例如用户可能处于移动状态，在移动过程中观看手机100更为方便，或者用户距离便携计算机较远，用户就近观看手机100更为便利。下面介绍用户在手机上操作的情况下设备如何响应。
例如，用户在手机100上进行了第二操作(或者，也可以称为第一操作)，第二操作例如为触摸操作，可参考图5A，第二操作为用户用手指触摸手机的显示界面上的“文件3”这一文件图标的操作，这表示用户想要打开文件3。手机100的显示屏194上的触摸传感器180K可采集(或者，检测)第二操作的事件信息，或者说，手机100的显示屏194上的触摸传感器180K可捕捉第二操作，并获得第二操作的事件信息，第二操作的事件信息可指示第二操作。触摸传感器180K可将采集的第二操作的事件信息发送给第一管家软件。第二操作的事件信息例如包括手机100的标识，可选的，还可以包括第二操作的位置信息等。第二操作的位置信息例如为第二操作在显示屏194内的绝对位置信息。
第一管家软件获得第二操作的事件信息后，由于第二操作的事件信息包括手机100的标识，例如来自触摸传感器180K，因此第一管家软件可确定第二操作的事件信息对应于手机100，即，确定第二操作是在手机100上进行的操作，或者说，确定第二操作对应的文件图标(例如，“文件3”这一文件图标)位于手机100的显示界面上。那么，第一管家软件可以根据第二操作的位置信息确定第二操作所对应的文件，例如文件3，第一管家软件可以再根据文件3的类型确定能够打开文件3的应用，例如第一应用。在本申请实施例中，如果“软件”和“应用”这两个名词可互换，则“第一应用”也可以称为“第一软件”；或者，如果“软件”和“应用”不是同一层级的概念，不能互换，则可认为第一应用内设置了一个或多个软件模块。其中，前文所述的第二应用和这里的第一应用可以是同一种应用，例如均为Microsoft office word应用，只是因为安装在不同的设备中，所以名称不同；或者，第一应用和第二应用也可以是不同的应用，例如第一应用为Microsoft office word应用，第二应用为WPS office word应用，但第一应用和第二应用都能打开同种类型的文件。
接着，第一管家软件可以通过第一应用在手机100上打开手机100的本地文件***中存储的文件3，可参考图5B，为手机100上打开了文件3的示意图，图5B中的界面204即表示手机100的显示屏194上打开的文件3的界面。在手机100上打开文件后，用户可调整界面204的大小。
在这种方式下，在手机100上打开了文件3，则在便携计算机上不会打开文件3。
用户可在手机100上通过第一应用观看文件3，用户也可以在手机100上通过第一应用对文件3进行编辑操作，例如可在文件3中删除内容、增加内容或修改内容等。用户在对文件3操作完毕后，可以保存文件3，则手机100可以更新手机100的本地文件***中所存储的文件3的数据。
可参考图6，为采用本申请实施例如上所提供的方法后，在多屏协同模式下打开文件的过程的一种示意图。
图6中的1，表示用户点击手机100的显示界面上显示的文件，手机100上安装的第一管家软件(例如，图6中的手机助手)获得用户的点击操作信息，并进行点击响应。或者，图6中的1，表示用户点击便携计算机显示屏上的手机的投屏界面202中显示的文件，便携计算机上安装的第二管家软件(例如，图6中的PC管家)获得用户的点击操作信息，并进行点击响应。
图6中的2，表示第二管家软件将获得的用户的点击操作信息发送给第一管家软件。
图6中的3，表示第一管家软件进行焦点判断，即判断用户的操作焦点位于哪里。在本申请实施例中，例如第一管家软件可根据点击响应的参数确定用户的焦点。例如，如果是第二管家软件发来的点击操作信息，则第一管家软件在进行点击响应时，可将点击响应的参数的取值设置为第一值，而如果是手机100内的传感器(例如触摸传感器180K等)发来的点击操作信息，则第一管家软件在进行点击响应时，可将点击响应的参数的取值设置为第二值。这样第一管家软件在进行焦点判断时，根据点击操作的参数的不同取值就可以确定用户的操作究竟针对哪个设备，或者说，能够确定用户的操作焦点位于哪个设备。
图6中的4，就表示第一管家软件根据焦点判断的结果，会进行不同的处理。
如果第一管家软件确定用户的操作焦点位于便携计算机，则第一管家软件可进行文件打开截断处理。这是因为，用户的操作焦点位于便携计算机，因此文件需要在便携计算机上打开，手机100上不打开该文件，因此手机100需要对原本需要进行的打开该文件的操作进行截断。
图6中的5，表示第一管家软件获取该文件的路径。这里所述的该文件的路径，是指该文件的绝对路径，即，该文件在手机100中的存储路径。
图6中的6，表示第一管家软件将在手机中的分布式文件管理***中创建软链接，该软链接指向第一存储路径，第一存储路径为该文件在手机中的存储路径，例如该文件在手机的SD中的存储路径或该文件的URL等。另外，该软链接还与该文件的元数据相关联，该文件的元数据例如包括该文件的存储路径，可选的，还可以包括该文件的类型信息等。
图6中的7，表示手机100端的分布式文件管理***将该文件的元数据同步到便携计算机端的分布式文件管理***。
图6中的8，表示第一管家软件获得手机100端的分布式文件管理***中创建的该软链接的路径。
图6中的9，表示第一管家软件将手机100端的分布式文件管理***中创建的该软链 接的路径发送给第二管家软件。另外，第一管家软件也能够获得该文件的元数据，例如该文件的类型信息等，第一管家软件也可以将获得的该文件的元数据发送给第二管家软件。
图6中的10和11，表示第二管家软件根据该文件的类型信息等，调用能够打开该文件的应用，另外，第二管家软件也将软链接的路径发给该应用。图6以该应用是Microsoft office应用为例。
图6中的12，表示office应用根据该软链接的路径，打开该软链接。
图6中的13，表示便携计算机端的分布式文件管理***根据该软链接对应的元数据(例如根据元数据所包括的该文件的存储路径)，到手机100端的分布式文件管理***中请求获得该文件。
图6中的14，表示手机100端的分布式文件管理***读取该软链接实际指向的文件，例如手机100端的分布式文件管理***从手机100的本地文件***中读取该文件。另外，手机100端的分布式文件管理***还将读取的文件发送给便携计算机端的分布式文件管理***，从而便携计算机端的office应用能够打开该文件。另外，便携计算机还可将文件3的数据存储在便携计算机中，例如便携计算机可通过第二应用可将文件3的数据存储在便携计算机的本地文件***中，例如可作为临时文件来存储，用户可以通过便携计算机端的第二应用对文件3进行修改、删除内容或增加内容等操作，则便携计算机的本地文件***存储的该临时文件可以得到更新。在更新后，便携计算机可将更新的文件发送给手机100，使得手机100能够根据该更新的文件更新手机100的本地文件***中存储的原文件。
图6中的5～14介绍的都是在便携计算机上打开文件的操作。或者，如果第一管家软件确定用户的操作焦点位于手机100，那么手机100可以调用能够打开该文件的应用，例如第一应用，接着可参考图6中的15，第一应用根据该文件在手机100的本地文件***中的存储路径打开该文件。
针对第一设备里的同一个文件，采用本申请实施例提供的方法后，在第一设备上操作和在第一设备镜像到第二设备上的协同窗口(例如投屏界面202)内操作，最终的体验效果是不一样的，即使在多屏协同场景下，第一设备也可以根据用户当前的焦点(例如用户的操作所针对的设备)，智能地选择通过其中一个设备去打开-编辑-保存相应的文件，用户无需离开或者切换当前聚焦的屏幕，就能够完成办公等需求，以给予用户更佳的预览和编辑体验。
在前面介绍的方式中，如果用户在手机100上进行了操作，则手机100就会打开相应的文件。接下来再介绍一种方式，在这种方式下，如果用户在手机100上进行了操作，手机100可以为用户提供选项，由用户选择是在手机100上打开对应的文件还是在便携计算机上打开对应的文件。通过这种方式，使得最终打开文件的设备更为符合用户的需求。
例如，用户在手机100上进行了第二操作，第二操作例如为触摸操作，第二操作用于打开第一文件。可继续参考图5A，第二操作为用户用手指触摸手机的显示界面上的“文件3”这一文件图标的操作，这表示用户想要打开文件3。手机100的显示屏194上的触摸传感器180K可捕捉第二操作，并获得第二操作的事件信息，触摸传感器180K可将第二操作的事件信息发送给第一管家软件。第二操作的事件信息例如包括手机100的标识，可选的，还可以包括第二操作的位置信息等。第二操作的位置信息例如为第二操作在显示屏194内的绝对位置信息。应理解：本文所涉及的触摸操作可以被悬浮操作，语音指令等替换。本文中以触摸操作为例进行说明，但这并不构成对本申请实施例的限制。
第一管家软件获得第二操作的事件信息后，由于第二操作的事件信息包括手机100的标识，因此第一管家软件可确定第二操作的事件信息对应于手机100，即，确定第二操作是在手机100上发生的操作，或者说，确定第二操作对应的文件图标(例如，“文件3”这一文件图标)位于手机100的显示界面上。那么，第一管家软件可以通过显示屏194输出提示信息205，该提示信息205可包括一个或多个选项，该提示信息205可用于确定打开文件3的设备。例如可参考图7A，为手机100的显示屏194上显示的一种提示信息205的示意图。该提示信息205以包括4个选项为例，其中的一个选项为“电脑端应用”，这表示在协同设备(例如便携计算机)上打开文件3，剩余的3个选项分别为“1”、“2”和“3”，分别代表应用1、应用2和应用3，这3个应用都是手机100上的应用，也都是能够打开文件3的应用。其中，手机100可能有一个或多个应用能打开第一文件，如果手机100上只有一个应用能打开第一文件，则提示信息205除了显示“电脑端应用”这个选项外只显示另一个选项即可；或者，如果手机100上有多个应用能打开第一文件，则提示信息205除了显示“电脑端应用”这个选项之外，可显示能够打开第一文件的全部应用对应的选项或部分应用对应的选项。如果用户选择了“电脑端应用”，则表明用户选择在协同设备上打开第一文件，而用户选择了除“电脑端应用”之外的其他的任意一个应用，则表明用户选择在手机100上通过该应用打开第一文件。
可参考图7B，例如用户用手指触摸了提示信息205包括的“电脑端应用”这一选项，这表明用户选择了“电脑端应用”，则手机100端的分布式文件管理***可以将第一操作所对应的第一文件的元数据同步到便携计算机端的分布式文件管理***。关于文件的元数据，可参考前文的介绍。以及在便携计算机获得第一文件的元数据后的操作过程，也可参考前文对于在便携计算机上打开文件3的过程的介绍。
可选的，在图7A或图7B中，手机100输出的提示信息205可以不包括便携计算机上的具体选项，即，用户无法根据手机100输出的提示信息205选择便携计算机上的具体的应用。例如图7A或图7B中，如果用户要选择在便携计算机上打开，则可以选择“电脑端应用”这个选项，而该选项本身只对应便携计算机，并不对应便携计算机上的具体的应用。如果用户选择在便携计算机上打开，便携计算机再根据第一文件的类型选择相应的应用打开第一文件。或者还有一种方式，手机100所输出的提示信息205也可以包括便携计算机上的选项。例如可参考图7C，为手机100的显示屏194上显示的另一种提示信息205的示意图。该提示信息205以包括5个选项为例，这5个选项分别为“1”、“2”、“3”、“4”和“5”，分别表示应用1、应用2、应用3、应用4和应用5。其中的应用4和应用5是便携计算机上的应用，也都是能够打开文件3的应用，这表示在协同设备(例如便携计算机)上打开文件3；应用1、应用2和应用3都是手机100上的应用，也都是能够打开文件3的应用。在图7B中，“4”和“5”的显示字体较大较粗，表示应用4和应用5是便携计算机上的应用，或者也可以通过其他提示方式来表示相应的应用是便携计算机上的应用，例如可显示提示文字等。通过这种方式，用户可以选择在便携计算机上究竟通过哪种应用来打开第一文件，使得用户的观看体验更好。
或者，可参考图7D，例如用户用手指触摸了“1”这一选项，这表明用户选择了在手机100上通过“1”对应的应用1打开第一文件，则第一管家软件可以调用“1”对应的应用1打开文件3。在第一管家软件调用“1”对应的应用1打开文件3之后的操作过程，也可参考前文对于在手机100上打开文件3的过程的介绍。
例如，有时用户虽然是在手机100上操作，但实际上是希望在便携计算机上将相应的文件展示给其他用户观看，如果是这种场景，则通过本申请实施例提供的技术方案，用户就可以选择在便携计算机上打开，从而完成展示过程。可见，通过本申请实施例提供的技术方案，为用户提供了选择机会，更便于用户选择合适的设备打开相应的文件。
在多屏协同模式下，第二设备上显示的协同窗口是第一设备的显示界面的镜像，所以按照现有的方式，用户无论在第一设备还是在第二设备的协同窗口内操作，操作过程都是同源的，最终也都会在第二设备上真正响应用户的操作。而本申请实施例是通过技术实现，打破了这种“同源”的壁垒，第一设备会增加判断机制，针对同一个文件，如果用户在不同的设备上进行操作，则可能会通过不同的设备来打开该文件，从而产生了区别于当前技术的差异化体验，能够给予用户更好的使用体验。而且用户也不需要在退出多屏协同模式后才能在第一设备上打开相应的文件，简化了用户的操作步骤，也减少了设备的响应过程，有助于节省设备的功耗。
结合上述实施例及相关附图，本申请实施例提供第一种打开文件的方法，该方法可以应用于多屏协同场景中。示例性的，该方法涉及第一设备和第二设备，第一设备的结构可以参考图1。下面请参考图8，介绍该方法的流程。为了更便于理解，在下文的介绍过程中，以第一设备是手机100，第二设备是便携计算机为例。
