随着科技的进步，智能手机、个人电脑、平板等智能终端设备的应用越来越广泛。在实际办公场景下，用户希望在不同的智能终端设备上共享文件资源。实现不同设备之间多屏互动，有效地提高多台设备间的文件资源传输效率。
目前，现有技术中有以下两种常用的文件分享方法，使用设备协同技术和WiFi-P2P直连技术建立设备间的连接，可实现文件分享。其中，使用设备协同技术，在两台设备建立协同的情况下，能够实现对文件进行跨设备拖拽并传输，例如，在第一设备上发起文件拖拽，被拖拽文件离开第一设备时携带相关信息至第二设备，第二设备给予相应地处理；使用WiFi-P2P技术建立智能终端设备之间点对点的连接，数据量较大的文件通过WiFi网络传输，数据量较小的文件通过蓝牙信道传输。
然而，上述两种文件分享技术，通常只建立在两台设备之间，且仅在该两台设备之间进行文件的拖拽和文件传输。对于一些多样化或复杂的应用场景(如多台设备之间的文件分享等)，还不能提供更好的文件分享体验。
发明内容
本发明实施例所要解决的技术问题在于，提供一种文件传输方法及相关设备，提升多设备间的文件分享效率和用户体验。
第一方面，一种文件传输的方法，其特征在于，应用于多设备协同系统中的第一设备，所述多设备协同系统中包括N个设备，所述N个设备中的任意一个设备与所述N个设备中的至少一个其他设备建立协同；所述第一设备为所述N个设备中的任意一个；N为大于2的整数；所述方法包括：所述第一设备显示第一界面；所述第一界面包括所述第一设备的显示屏界面，以及与所述第一设备建立协同的M个第二设备对应的协同窗口；M为大于或者等于0的整数；接收作用于所述第一界面上对目标文件的第一拖拽操作；通知所述N个设备中的其他设备监听所述第一拖拽操作释放位置；所述释放位置包括所述N个设备中任意一个设备的界面或所述协同窗口；检测所述第一拖拽操释放位置；控制将所述目标文件发送至所述N个设备中与所述释放位置匹配的设备。
在本发明实施例中，多设备协同系统中可存在三个及三个以上的设备，若设备间需要进行文件传输，在所述第一设备的第一界面上选中目标文件，对目标文件进行拖拽操作，所述拖拽操作包括但不限于触屏将目标文件拖拽、使用鼠标等外设将目标文件拖拽。同时，所述第一设备会发送广播消息通知该系统中的其他所有设备，当前有目标文件待分享，让系统中 的所有设备都监听拖拽操作释放的位置，可让该系统中的设备都准备接收该目标文件。进一步地，第一设备在检测到拖拽操作的释放位置后，可控制将目标文件发送给与所述释放位置匹配的设备。通过实施本发明实施例的方法，在多设备协同系统中每一个设备都可在不断开协同的情况下发送或接收目标文件，可避免在未建立协同的两个设备上进行文件传输时，断开与其他设备建立的协同，再重新建立新的协同进行文件传输的情况，从而实现跨多台设备文件传输，提高了多设备协同下文件传输效率同时也精简了用户操作。
在一种可能的实现方式中，所述目标文件为所述第一设备上存储的文件；所述第一拖拽操作的起始位置在所述显示屏界面上；所述目标文件为所述M个第二设备中起始第二设备上存储的文件；所述第一拖拽操作的起始位置在所述起始第二设备对应的协同窗口中。在本发明实施例中，在第一界面上包括了第一设备的显示屏界面和M个第二设备对应的协同窗口，在第一界面上对目标文件进行拖拽操作，目标文件若在第一设备的显示屏界面上且目标文件在第一设备的显示屏界面上被拖拽，而不是在M个第二设备对应的协同窗口中被拖拽，则表示该目标文件存储在第一设备上，确定第一设备可发送目标文件。在另一种情况下，目标文件若在其中一个设备的协同窗口上且目标文件在该协同窗口上被拖拽，而不是在第一设备的显示屏界面被拖拽，则表示目标文件存储在该协同窗口所对应的设备上，确定第一设备可控制该协同窗口所对应的设备发送目标文件。
在一种可能的实现方式中，所述目标文件为所述第一设备上存储的文件；所述控制将所述目标文件发送至所述N个设备中与所述释放位置匹配的设备，包括：当检测到所述第一拖拽操作的释放位置在第三设备的显示屏界面，或当检测到所述第一拖拽操作的释放位置在所述第三设备在所述N个设备中其他设备上的协同窗口中时，则控制所述第一设备将所述目标文件发送至所述第三设备；所述第三设备包括所述N个设备中与所述第一设备未建立协同的设备。在本发明实施例中，当目标文件在第一设备的第一界面被拖拽后，若目标文件被释放在多设备协同系统中任意一个设备的显示屏界面或设备对应的协同窗口上时，则代表目标文件需发送给与该释放位置所匹配的设备，该设备与第一设备可无需建立协同。例如，当平板与手机建立协同且平板上有手机的协同窗口，且平板与电脑建立协同的情况下，在平板屏幕上用户可对手机的协同窗口中的待分享文件进行拖拽操作，将待分享文件发送给电脑。从而可实现在第一设备无需断开与其他设备的协同的情况下，可通过对目标文件进行拖拽操作与未建立协同的设备进行文件传输。
在一种可能的实现方式中，所述方法还包括：获取所述目标文件的文件信息；所述文件信息包括所述目标文件的文件名、文件内容、文件大小信息；判断与所述释放位置匹配的设备是否满足接收所述目标文件的条件；若满足，则确定与所述释放位置匹配的设备接收所述目标文件的存储路径。在本发明实施例中，若两个设备通过对目标文件进行拖拽操作实现文件分享，则发送设备(存储目标文件的设备，如第一设备或M个第二设备中的一个)需要判断接收设备是否有充足的存储空间来存储目标文件。因此，发送设备在获取目标文件的文件信息后，可以先将目标文件的大小发送给接收设备，判断该设备是否有空间来存储目标文件，若有充足的存储空间，则确定目标文件在接收设备上的存储路径，继而发送设备可将目标文件成功发送到该存储路径。
在一种可能的实现方式中，所述则控制所述第一设备将所述目标文件发送至第三设备，包括：建立数据传输通道；所述数据传输通道用于传输所述目标文件的所述文件信息；若所述第一设备与所述第三设备建立直接连接，则通过所述数据传输通道将所述文件信息发送到所述第三设备的所述存储路径；若所述第一设备与所述第三设备建立间接连接，则通过所述 数据传输通道将所述文件信息发送给中继设备，通过所述中继设备将所述文件信息转发到所述第三设备所述存储路径，其中所述中继设备为与所述第一设备建立直接连接同时与所述第三设备建立直接连接的设备。在本发明实施例中，在多设备协同系统中，由于使用了不同的组网技术，从而可实现更多设备的连接同时不用断开设备间的协同。但不同的组网技术可存在不同的组网方式可导致各设备间的连接关系发生变化。当第一设备为发送设备，第三设备作为接收设备时，第一设备和第三设备在使用不同的组网方式下可建立直接连接也可建立间接连接。若第一设备与第三设备建立直接连接(如使用自组网技术连接各设备)，则第一设备可将目标文件的文件信息直接发送给第三设备，若第一设备与第三设备未建立直接连接而是通过中继设备(多设备协同系统里N个设备中可与第一设备建立直接连接同时也可与第三设备建立直接连接的设备)建立了间接连接(如使用WiFi-P2P技术组网实现设备间一对多的连接)，则第一设备将目标文件的文件信息先发送给中继设备，中继设备在将目标文件的文件信息转发给第三设备，从而实现多台设备文件传输。
在一种可能的实现方式中，所述目标文件为所述M个第二设备中起始第二设备上存储的文件；所述控制将所述目标文件发送至所述N个设备中与所述释放位置匹配的设备，包括：当检测到所述第一拖拽操作的释放位置在第三设备的显示屏界面，或检测到所述第一拖拽操作的释放位置在所述第三设备在所述N个设备中其他设备上的协同窗口中，则控制所述起始第二设备将所述目标文件发送至所述第三设备。在本发明实施例中，当协同窗口中的目标文件在第一界面上被拖拽后，若目标文件被释放在多设备协同系统中任意一个设备的显示屏界面或该设备对应的协同窗口上时，则代表目标文件需发送给与该释放位置所匹配的设备。可选的，第三设备可为M个第二设备中的一个设备。例如，当电脑同时与手机和平板建立协同且在电脑上有手机和平板的协同窗口，且手机与平板无需建立协同，用户可选中平板协同窗口中的文件，将该文件拖拽到手机协同窗口中，此时可实现平板上的文件可以通过拖拽操作直接分享给手机。从而实现在无需断开与其他设备协同的情况下，通过对目标文件进行拖拽操作与未建立协同的设备进行文件传输，精简了文件传输操作。
在一种可能的实现方式中，所述控制所述起始第二设备将所述目标文件发送至所述第三设备，包括：建立数据传输通道；所述数据传输通道用于传输所述目标文件的所述文件信息；若所述起始第二设备与所述第三设备建立直接连接，则通过所述数据传输通道将所述文件信息发送到与所述释放位置匹配的设备的所述存储路径；若所述起始第二设备与所述第三设备建立间接连接，则通过所述数据传输通道将所述文件信息发送给中继设备，通过所述中继设备将所述文件信息转发给与所述释放位置匹配的设备所述存储路径，其中所述中继设备为与所述起始第二设备建立直接连接同时与所述第三设备建立直接连接的设备。在本发明实施例中，在多设备协同系统中，由于使用了不同的组网技术，从而可实现更多设备的连接同时不用断开设备间的协同。但不同的组网技术可存在不同的组网方式可导致各设备间的连接关系发生变化。当起始第二设备作为发送设备时，起始第二设备和第三设备在使用不同的组网方式下可建立直接连接也可建立间接连接。如起始第二设备与第三设备可建立直接连接(如使用自组网技术进行组网)，则起始第二设备可将目标文件的文件信息直接发送给第三设备，如起始第二设备与第三设备未建立直接连接而是通过中继设备(如第一设备)建立了间接连接(如使用WiFi-P2P技术组网实现设备间一对多的连接)，则起始第二设备将目标文件的文件信息先发送给中继设备，中继设备在将目标文件的文件信息转发给第三设备，从而实现多台设备文件传输。
在一种可能的实现方式中，所述方法还包括：获取所述目标文件的第一信息；所述第一 信息包括所述目标文件的文件类型信息、文件数量信息、文件排列顺序信息中的一个或多个；根据所述第一信息，生成所述目标文件的拖拽效果集合；根据所述目标文件的拖拽效果集合显示与第四设备匹配的拖拽效果；所述第四设备为所述第一拖拽操作的拖拽轨迹经过的设备，或经过的设备上的协同窗口对应的设备。在本发明实施例中，在对目标文件进行拖拽操作过程中，目标文件可被跨设备拖拽，在拖拽轨迹上可经过多个设备，所经过的多个设备为所述第四设备，不同的设备可存在不同的操作系统，例如，若拖拽轨迹经过手机和电脑，手机使用Android系统，但电脑使用Windows系统。针对不同的操作系统在目标文件被拖拽过程中显示与操作系统相适应的文件拖拽效果。通过使用本发明实施例的方法，在获取到目标文件的文件类型信息、文件数量信息等与目标文件相关的信息后，可根据这些信息生成一个拖拽效果集合，拖拽效果集合中包括了一个或多个文件拖拽效果，然后根据拖拽轨迹所经过的设备的操作系统显示相适应的文件拖拽效果。
第二方面，一种文件传输的方法，其特征在于，应用于多设备协同系统中的第三设备，所述多设备协同系统中包括N个设备，所述N个设备中的任意一个设备与所述N个设备中的至少一个其他设备建立协同；所述第三设备为所述N个设备中的任意一个设备；N为大于2的整数；所述方法包括：接收所述第一设备发起的监听第一拖拽操作释放位置的通知；所述第一拖拽操作为在所述第一界面上对目标文件发起拖拽；所述第一界面包括所述第一设备的显示屏界面，以及与所述第一设备建立协同的M个第二设备对应的协同窗口；M为大于或者等于0的整数；监听所述第一拖拽操作的释放位置；接收第一设备所控制发送的所述目标文件；发送广播通知所述多设备协同系统中的其他设备所述目标文件已被成功接收。在本发明实施例中，多设备协同系统中可存在三个及三个以上的设备，若设备间需要进行文件传输，在第一设备上发起对目标文件的分享，第三设备会接收到第一设备发起的监听目标文件释放位置的通知，此时第三设备会做好接收目标文件的准备，当检测到该目标文件释放在第三设备上时，第一设备可控制将目标文件发送给第三设备，此时第三设备会接收该目标文件，在第三设备成功接收该目标文件后会发送广播通知多设备协同系统中的其他所有设备目标文件已经成功接收，无需在等待接收。通过实施本发明实施例的方法，在多设备协同系统中每一个设备都可在不断开协同的情况下都可接收目标文件，可避免在未建立协同的两个设备上进行文件传输时，断开与其他设备建立的协同，再重新建立新的协同进行文件传输的情况，从而实现跨多台设备文件传输，提高了多设备协同下文件传输效率同时也精简了用户操作。
在一种可能的实现方式中，所述接收第一设备所控制发送的所述目标文件，包括：与存储所述目标文件的设备建立数据传输通道；接收所述目标文件的文件信息；所述文件信息包括所述目标文件的文件名、文件内容、文件大小信息。在本发明实施例中，第三设备会接收到来自发送设备发送的目标文件的大小的信息，在判断第三设备有足够的空间接收该目标文件后，第三设备可接收到目标文件的文件信息。

可以理解的是，本发明实施例示意的结构并不构成对电子设备100的具体限定。在本申请另一些实施例中，电子设备100可以包括比图示更多或更少的部件，或者组合某些部件，或者拆分某些部件，或者不同的部件布置。图示的部件可以以硬件，软件或软件和硬件的组合实现。
处理器110可以包括一个或多个处理单元，例如：处理器110可以包括应用处理器(application processor，AP)，中央处理器(central processing unit，CPU)，图形处理器(graphics processing unit，GPU)，神经网络处理器(neural-network processing unit，NPU)，调制解调处理器，图像信号处理器(image signal processor，ISP)，控制器，存储器，视频编解码器，数字 信号处理器(digital signal processor，DSP)，基带处理器等。其中，不同的处理单元可以是独立的器件，也可以集成在一个或多个处理器中。在一些实施例中，电子设备100也可以包括一个或多个处理器110。
其中，控制器可以是电子设备100的神经中枢和指挥中心。控制器可以根据指令操作码和时序信号，产生操作控制信号，完成取指令和执行指令的控制。
处理器110中还可以设置存储器，用于存储指令和数据。在一些实施例中，处理器110中的存储器为高速缓冲存储器。该存储器可以保存处理器110刚用过或循环使用的指令或数据。如果处理器110需要再次使用该指令或数据，可从所述存储器中直接调用。避免了重复存取，减少了处理器110的等待时间，因而提高了电子设备100的效率。
在一些实施例中，处理器110可以包括一个或多个接口。接口可以包括集成电路(inter-integrated circuit，I2C)接口，集成电路内置音频(inter-integrated circuit sound，I2S)接口，脉冲编码调制(pulse code modulation，PCM)接口，通用异步收发传输器(universal asynchronous receiver/transmitter，UART)接口，移动产业处理器接口(mobile industry processor interface，MIPI)，通用输入输出(general-purpose input/output，GPIO)接口，用户标识模块(subscriber identity module，SIM)接口，和/或通用串行总线(universal serial bus，USB)接口等。
I2C接口是一种双向同步串行总线，包括一根串行数据线(serial data line，SDA)和一根串行时钟线(derail clock line，SCL)。在一些实施例中，处理器110可以包含多组I2C总线。处理器110可以通过不同的I2C总线接口分别耦合触摸传感器180K，充电器，闪光灯，3D摄像模组193等。例如：处理器110可以通过I2C接口耦合触摸传感器180K，使处理器110与触摸传感器180K通过I2C总线接口通信，实现电子设备100的触摸功能。
I2S接口可以用于音频通信。在一些实施例中，处理器110可以包含多组I2S总线。处理器110可以通过I2S总线与音频模块170耦合，实现处理器110与音频模块170之间的通信。在一些实施例中，音频模块170可以通过I2S接口向无线通信模块160传递音频信号，实现通过蓝牙耳机接听电话的功能。
PCM接口也可以用于音频通信，将模拟信号抽样，量化和编码。在一些实施例中，音频模块170与无线通信模块160可以通过PCM总线接口耦合。在一些实施例中，音频模块170也可以通过PCM接口向无线通信模块160传递音频信号，实现通过蓝牙耳机接听电话的功能。所述I2S接口和所述PCM接口都可以用于音频通信。

随着互联网的高速发展，越来越多年轻人喜欢用拍Vlog的方式记录下自己生活中的点点滴滴并上传到网络，与自己的好友和粉丝进行分享。这促使着手机摄像功能的不断进步，人们慢慢放下沉重的相机，开始掏出手机随时随地录制视频素材。完成一个Vlog视频需要前期写稿子、拍摄视频素材，后期进行剪辑，使之成为一个连续的有完整内容的视频。在Vlog视频制作过程中难免会遇到这样的情况，为了使拍摄画面更加清晰，拍摄者一般会使用手机后摄进行摄像，在录制一些需要拍摄者入境的画面时，可借助一台平板与手机建立协同作为视频画面监控屏，使得拍摄者可以随时看到拍摄效果。但当拍摄者想要把视频素材上传到电脑进行剪辑时，手机必须要断开与平板的协同，然后在与电脑建立协同上传文件资料，这样繁琐的操作会给拍摄者带来一些不便。所以在此情境下，使用本发明实施例可实现手机与平板建立协同，手机的显示屏可投到平板上，平板与电脑建立协同，电脑可随时把稿子发送给平板，此时拍摄者只用看着平板就能完成视频录制。并且手机可在不与电脑建立协同的情况下，可把手机上的视频素材资料直接拖拽并传输给电脑，然后使用电脑进行后期剪辑，这样极大地方便了拍摄者制作Vlog视频的过程。
场景二，基于企业会议的文件传输场景：
随着科技的进步，越来越多的企业开始注重高效办公。在传统的企业会议中，需要主讲人提前准备好文件资料并进行打印，分发给每一个参会人员，并且在会议中如果有人对文件资料进行修改是没有办法快速同步给其他参会人员的。在此情况下，如果将参会人员的个人电子设备进行彼此连接，会议主讲人就可把自己准备的文件资料直接传给其他参会人员的个人电子设备，并且如果参会人员对文件资料进行修改后，修改人可把修改后的文件资料传给 其他参会人员的个人电子设备。通过使用本发明实施例可实现，在不用断开各个电子设备协同的情况下，可实现多个电子设备(三个及三个以上电子设备)进行文件传输，这样提高了企业会议中的办公效率。
可以理解的是，上述两种应用场景的只是本发明实施例中的几种示例性的实施方式，本发明实施例中的应用场景包括但不仅限于以上应用场景。
下面结合附图对本申请的实施例进行描述。
基于上述提出的技术问题以及本申请中对应的应用场景，也为了便于理解本发明实施例，下面先对本发明实施例所基于的系统架构进行描述。请参考见图2，图2是本发明实施例提供的一种文件传输的系统架构示意图，该系统用于解决多台智能终端设备之间文件资源传输效率低的问题。该系统架构中可以包括N个设备，述N个设备中的任意一个设备与所述N个设备中的至少一个其他设备建立协同；N为大于2的整数。其中，所述N个设备中的任意一个设备都可为上述图1A中所述的电子设备100，其中，

具体地，所述释放位置包括N个设备中任意一个设备的界面或所述协同窗口，所述第一拖拽操作释放位置为用户在第一界面上释放目标文件的位置。例如，如图5C所示，图5C为多设备协同系统中第一拖拽操作释放位置(以3个设备为例)示意图，图中用户在第一界面上的手机协同窗口中对C文件发起拖拽操作，此时平板会发送广播消息通知多设备协同系统中的电脑、平板、手机有文件拖拽操作发起，让系统中的每一个设备都做好接收C文件的准备，此时每一个设备会监听文件拖拽操作的释放位置且每一个设备都可得知C文件来源于手机。
步骤S404：第三设备接收第一设备发起的监听第一拖拽操作释放位置的通知。
具体地，所述第三设备对所述第一拖拽操作释放位置所对应的设备。例如，如图5C所示，图5C为多设备协同系统中第一拖拽操作释放位置(以3个设备为例)示意图，图中用户在第一界面上的手机协同窗口中对C文件发起拖拽操作，第三设备可为电脑也可为平板，此时电脑和平板都会接收到第一设备发起的监听第一拖拽操作释放位置的通知，从而得知在手机上有C文件待分享，时刻准备接收C文件。
步骤S405：第三设备监听所述第一拖拽操作释放位置。
具体地，所述第三设备在得知在第一设备上有目标文件待分享后，就时刻监听所述第一拖拽操作释放位置是不是对应在自己的界面上。例如，如图5C所示，图5C为多设备协同系统中第一拖拽操作释放位置(以3个设备为例)示意图，图中用户在第一界面上的手机协同窗口中对C文件发起拖拽操作，第三设备可为电脑也可为平板。当电脑作为第三设备时，电脑会时刻监听C文件被释放的位置，当C文件释放在自己的显示屏界面上时就接收C文件。
步骤S406：第一设备检测所述第一拖拽操作所述释放位置。
具体地，在所述第一界面上的释放位置可包括所述释放位置包括所述N个设备中任意一个设备的显示屏界面或该设备对应的协同窗口。此时第三设备为第一拖拽操作释放位置所对应的设备。例如，如图5C所示，图5C为三个设备系统中第一拖拽操作释放位置示意图，用户在第一界面上的手机协同窗口中对C文件发起拖拽操作，可沿轨迹1将C文件释放在平板的显示屏界面，则平板会检测到所述释放位置为平板的显示屏界面，此时第三设备为平板，代表需将C文件发送给平板。也可沿轨迹2将C文件释放在电脑的显示屏界面，平板会检测到所述释放位置为电脑显示屏界面，此时第三设备为电脑，代表需将C文件发送给电脑。
步骤S407：第一设备控制将所述目标文件发送至所述N个设备中与所述释放位置匹配的设备。
具体地，所述控制将所述目标文件发送至所述N个设备中与所述释放位置匹配的设备包括第一设备发送目标文件至与所述释放位置匹配的设备和第一设备控制其他设备将目标文件发送至与所述释放位置匹配的设备。例如，如图5D所示，图5D为多设备协同系统中发送目标文件(以3个设备为例)示意图，若当用户在第一界面上选中C文件并沿着轨迹5拖拽C文件，在电脑的显示屏界面上释放拖拽操作，则平板会控制手机将C文件发送至电脑。若用户在第一界面上选中b文件并沿着轨迹6拖拽b文件，在手机的协同窗口上释放拖拽操作， 则平板会将b文件发送至手机。
步骤S408：第三设备接收第一设备所控制发送的所述目标文件。
具体地，当第一设备控制将所述目标文件发送至第三设备后，第三设备可将所述目标文件存储在设备中。例如，如图5D所示，图5D为多设备协同系统中发送目标文件(以3个设备为例)示意图，若当用户在第一界面上选中C文件并沿着轨迹5拖拽C文件，在电脑的显示屏界面上释放拖拽操作，则平板会控制手机将C文件发送至电脑。此时电脑作为第三设备，会接收C文件，并将C文件存储在本地。若用户在第一界面上选中b文件并沿着轨迹6拖拽b文件，在手机的协同窗口上释放拖拽操作，则平板会将b文件发送至手机。此时手机作为第三设备，会接收b文件，并将b文件存储在本地。
步骤S409：第三设备发送广播通知所述多设备协同系统中的其他设备所述目标文件已成功接收。
具体地，当第三设备在成功接收了目标文件后，会发送广播通知多设备协同系统中的其他设备所述目标文件已经被成功接收，其他设备无需在等待接收。例如，如图5D所示，图5D为多设备协同系统中发送目标文件(以3个设备为例)示意图，若当用户在第一界面上选中C文件并沿着轨迹5拖拽C文件，在电脑的显示屏界面上释放拖拽操作，则平板会控制手机将C文件发送至电脑。在电脑成功接收C文件后，会通知多设备协同系统中的平板和手机，C文件已经被成功接收，无需在等待接收。
通过使用本发明实施例的方法，在多设备协同系统中每一个设备都可在无需断开协同的情况下发送或接收目标文件，可避免在未建立协同的两个设备上进行文件传输时，断开与其他设备建立的协同，再重新建立新的协同进行文件传输，从而实现跨多台设备便捷地进行文件传输，提高了多设备协同下文件资源传输效率并精简了用户操作，提升了用户体验。
下面对本发明实施例所基于的具体方法架构进行描述。参见图6，图6是本申请实施例中的一种文件传输方法的详细流程示意图，下面将结合附图6并基于上述图2中的文件传输系统架构从第一设备和第三设备(如M个第二设备中的一个等)的交互侧对本申请实施例中的文件传输方法进行描述。需要说明的是，为了更详细的描述本申请实施例中的文件扫描方法，本申请在各个流程步骤中描述了相应的执行主体为第一设备或第三设备，但不代表本申请实施例只能通过所描述的执行主体进行对应的方法流程。
步骤S601：第一设备显示第一界面。
具体地，所述第一界面包括所述第一设备的显示屏界面，以及与所述第一设备建立协同的M个第二设备对应的协同窗口，M为大于或者等于0的整数。所述第一设备可通过显示屏194显示第一界面。例如，如图7A所示，图7A为多设备协同系统(以5个设备为例)示意图，图中该系统包括五个电子设备，五个电子设备分别为电脑、平板、手机1、手机2和手机3。在手机1与电脑建立协同且电脑上有手机1的协同窗口，且手机2与电脑建立协且电脑上有手机2的协同窗口，同时电脑与平板建立协同，且手机3与平板建立协同且平板上有手机3的协同窗口的情景下，电脑可作为所述第一设备，在电脑上可显示第一界面，此时所述M的取值为2，所述M个第二设备包括手机1和手机2，电脑的屏幕上有两个设备的协同窗口，电脑的屏幕上除去协同窗口位置的其他位置为第一设备的显示屏界面。
步骤S602：第一设备接收作用于所述第一界面上对目标文件的第一拖拽操作。
具体地，所述目标文件为待传输的文件，所述第一拖拽操作可包括但不限于通过使用第一设备的触摸传感器180K触屏将目标文件拖拽、使用鼠标等外设将目标文件拖拽。图7A为 多设备协同系统(以5个设备为例)示意图，图中该系统包括五个电子设备，五个电子设备分别为电脑、平板、手机1、手机2和手机3。需要说明的是，在手机1与电脑建立协同且电脑上有手机1的协同窗口，且手机2与电脑建立协同且电脑上有手机2的协同窗口，同时电脑与平板建立协同，且手机3与平板建立协同且平板上有手机3的协同窗口的情景下，电脑可作为所述第一设备，此时目标文件可为A文件、B文件、D文件、A4文件、B4文件。
在一种可能的实现方式中，所述目标文件为所述第一设备上存储的文件，所述第一拖拽操作的起始位置在所述显示屏界面上；所述目标文件为所述M个第二设备中起始第二设备上存储的文件；所述第一拖拽操作的起始位置在所述起始第二设备对应的协同窗口中。具体地，在第一界面上包括了第一设备的显示屏界面和M个第二设备对应的协同窗口，在第一界面上对目标文件进行拖拽操作，目标文件若在第一设备的显示屏界面上且目标文件在第一设备的显示屏界面上被拖拽，而不是在M个第二设备对应的协同窗口中被拖拽，则表示该目标文件存储在第一设备上，确定第一设备可发送目标文件。目标文件若在其中一个设备的协同窗口上且目标文件在该协同窗口上被拖拽，而不是在第一设备的显示屏界面被拖拽，则表示目标文件存储在该协同窗口所对应的设备上，确定第一设备可控制该协同窗口所对应的设备发送目标文件。例如，如图7B所示，图7B为多设备协同系统中目标文件(以5个设备为例)示意图，图中该系统包括五个电子设备，五个电子设备分别为电脑、平板、手机1、手机2和手机3。在手机1与电脑建立协同且电脑上有手机1的协同窗口，手机2与电脑建立协同且电脑上有手机2的协同窗口，同时电脑与平板建立协同，手机3与平板建立协同且平板上有手机3的协同窗口的情景下，电脑可作为所述第一设备。图中当用户需要对A4文件进行文件拖拽操作时，由于A4文件在电脑的显示屏界面上，因此可认为A4文件存储在电脑上，则电脑可接收到作用于电脑显示屏界面上对A4文件的拖拽操作。图中当用户需要对A文件、B文件、D文件进行文件拖拽操作时，需要说明的是，此时所述起始第二设备为手机1，由于A文件、B文件、D文件在电脑屏幕的协同窗口上，所以可认为A文件、B文件、D文件存储该协同窗口所对应的手机1上，则电脑可接收到作用于电脑屏幕的协同窗口上对A文件、B文件、D文件的拖拽操作。
步骤S603：第一设备显示与第四设备匹配的拖拽效果。

步骤S604：第一设备通知所述N个设备中的其他设备监听所述第一拖拽操作释放位置。
具体地，当在所述第一界面上对目标文件进行拖拽操作时，所述第一设备会发送广播消息通知该系统中的其他设备有目标文件待分享且区分目标文件来源，这样可让系统中的所有设备都监听拖拽操作释放的位置，可让该系统中的设备都准备接收目标文件。例如，如图7C所示，图中该系统包括五个电子设备，五个电子设备分别为电脑、平板、手机1、手机2和手机3。在手机1与电脑建立协同且电脑上有手机1的协同窗口，手机2与电脑建立协同且电脑上有手机2的协同窗口，同时电脑与平板建立协同，手机3与平板建立协同且平板上有手机3的协同窗口的情景下，电脑可作为所述第一设备。当用户在电脑的显示屏界面上选中目标文件A4文件时，电脑会发送广播消息通知多设备协同系统中的手机1、手机2、手机3、平板开始监听拖拽操作释放的位置，此时在该多设备协同系统中的所有设备可接收A4文件。
步骤S605：第三设备接收第一设备发起的监听第一拖拽操作释放位置的通知。
具体地，所述第三设备为所述第一拖拽操作释放位置所对应的设备。例如，如图7C所示，图中该系统包括五个电子设备，五个电子设备分别为电脑、平板、手机1、手机2和手机3。在手机1与电脑建立协同且电脑上有手机1的协同窗口，手机2与电脑建立协同且电脑上有手机2的协同窗口，同时电脑与平板建立协同，手机3与平板建立协同且平板上有手机3的协同窗口的情景下，电脑可作为所述第一设备。图中用户在第一界面上的电脑显示屏界面上对A4文件发起拖拽操作，多设备协同系统中的手机1、手机2、手机3、平板和电脑都可作为第三设备。此时当手机3作为第三设备时，手机3会接收到电脑发起的监听第一拖拽操作设备位置的通知，从而得知在电脑上有A4文件待分享，时刻准备接收A4文件。
步骤S606：第三设备监听所述第一拖拽操作释放位置。
具体地，所述第三设备在得知在第一设备上有目标文件待分享后，就时刻监听所述第一拖拽操作释放位置是不是对应在自己的设备上。例如，如图7C所示，图中该系统包括五个电子设备，五个电子设备分别为电脑、平板、手机1、手机2和手机3。在手机1与电脑建立协同且电脑上有手机1的协同窗口，手机2与电脑建立协同且电脑上有手机2的协同窗口，同时电脑与平板建立协同，手机3与平板建立协同且平板上有手机3的协同窗口的情景下，电脑可作为所述第一设备。图中用户在第一界面上的电脑显示屏界面上对A4文件发起拖拽操作，多设备协同系统中的手机1、手机2、手机3、平板和电脑都可作为第三设备。当手机3作为第三设备时，手机3会时刻监听A4文件被释放的位置，当A4文件释放在自己的协同窗口上时就接收A4文件。
步骤S607：第一设备检测所述第一拖拽操作释放位置。
具体地，所述释放位置可包括所述释放位置包括N个设备中任意一个设备的界面或协同窗口。此时第三设备为第一拖拽操作释放位置所对应的设备。如图7D所示，图7D为多设备协同系统中第一拖拽操作释放位置(以5个设备为例)示意图，用户在第一界面上的手机1协同窗口中对D文件发起拖拽操作，可沿轨迹8将D文件释放在手机2协同窗口上，则电脑会检测到所述释放位置为手机2的协同窗口，代表需将D文件发送给手机2。也可沿轨迹7将C文件释放在平板的显示屏界面，则电脑会检测到所述释放位置为平板显示屏界面，此时第三设备为平板，代表需将D文件发送给平板。
步骤S608：第一设备确定与所述释放位置匹配的设备接收所述目标文件的存储路径。
具体地，待分享的目标文件将被发送给所述释放位置匹配的设备后，存储在确定的存储路径下。在一种可能的实现方式中，获取所述目标文件的文件信息，所述文件信息包括所述目标文件的文件名、文件内容、文件大小信息，判断与所述释放位置匹配的设备是否满足接收所述目标文件的条件，若满足，则确定与所述释放位置匹配的设备接收所述目标文件的存储路径。具体地，若两个设备通过对目标文件进行拖拽操作实现文件传输，则发送设备需要判断第三设备是否有充足的存储空间来存储目标文件。当发送设备在获取目标文件的文件信息后，可选的，发送设备先将目标文件的大小发送给第三设备，判断该设备是否有空间来存储目标文件，若有充足的存储空间，则确定目标文件在第三设备上的存储路径，发送设备可将目标文件发送到该存储路径。例如，如图7C所示，当用户在电脑的显示屏界面上选中目标文件A4文件并对其进行文件拖拽操作，电脑在获取到A4文件的文件大小后，将文件大小发送给多设备协同系统中的其他设备，其他设备会提前计算存储的剩余空间判断是否可接收目标文件，若无法接收此目标文件则给予无法接收的提示，若可接收则会给予接收提示。电脑在接收到所述释放位置匹配的设备的提示后，当该设备与有存储空间来存储A4文件，继而可确定目标文件存储在该设备上的存储路径。
步骤S609：第一设备控制将所述目标文件发送至所述N个设备中与所述释放位置匹配的设备。
具体地，所述控制将所述目标文件发送至所述N个设备中与所述释放位置匹配的设备包括第一设备发送目标文件至与所述释放位置匹配的设备和第一设备控制其他设备将目标文件发送至与所述释放位置匹配的设备。
在一种可能的实现方式中，所述目标文件为所述第一设备上存储的文件；所述控制将所述目标文件发送至所述N个设备中与所述释放位置匹配的设备，包括：当检测到所述第一拖拽操作的释放位置在第三设备的显示屏界面，或当检测到所述第一拖拽操作的释放位置在所述第三设备在所述N个设备中其他设备上的协同窗口中时，则控制所述第一设备将所述目标文件发送至所述第三设备；所述第三设备包括所述N个设备中与所述第一设备未建立协同的设备。需要说明的是，当目标文件在第一设备的第一界面被拖拽后，若目标文件被释放在多设备协同系统中任意一个设备的显示屏界面或该设备对应的协同窗口上时，则代表目标文件需发送给与该释放位置所匹配的设备，该设备与第一设备可无需建立协同。例如，如图7E所示，图7E为多设备协同系统中文件拖拽(以5个设备为例)示意图，图中该系统包括五个电子设备，五个电子设备分别为电脑、平板、手机1、手机2和手机3。在手机1与电脑建立协同且电脑上有手机1的协同窗口，手机2与电脑建立协同且电脑上有手机2的协同窗口，同时电脑与平板建立协同，手机3与平板建立协同且平板上有手机3的协同窗口的情景下，电脑可作为所述第一设备。图中用户在电脑显示屏界面上选中目标文件A4文件，可将A4文件沿轨迹9移动，最后将其释放在手机3的协同窗口中。
在一种可能实现的方式中，所述则控制所述第一设备将所述目标文件发送至第三设备，包括，建立数据传输通道，所述数据传输通道用于传输所述目标文件的所述文件信息，若所述第一设备与所述第三设备建立直接连接，则通过所述数据传输通道将所述文件信息发送到所述第三设备的所述存储路径，若所述第一设备与所述第三设备建立间接连接，则通过所述数据传输通道将所述文件信息发送给中继设备，通过所述中继设备将所述文件信息转发到所述第三设备所述存储路径，其中所述中继设备为与第一设备建立直接连接同时与第三设备建立直接连接的设备。具体地，在多设备协同系统中，由于使用了不同的组网技术，从而可实 现更多设备的连接同时不用断开设备间的协同。但不同的组网技术可存在不同的组网方式可导致各设备间的连接关系发生变化。当第一设备为发送设备，第三设备作为接收设备时，第一设备和第三设备在使用不同的组网方式下可建立直接连接也可建立间接连接。若第一设备与第三设备建立直接连接(如使用自组网技术连接各设备)，则第一设备可将目标文件的文件信息直接发送给第三设备，若第一设备与第三设备未建立直接连接而是通过中继设备(多设备协同系统里N个设备中可与第一设备建立直接连接同时也可与第三设备建立直接连接的设备)建立了间接连接(如使用WiFi-P2P技术组网实现设备间一对多的连接)，则第一设备将目标文件的文件信息先发送给中继设备，中继设备在将目标文件的文件信息转发给第三设备，从而实现多台设备文件传输。例如，如图7E所示，图中用户在电脑显示屏界面上选中目标文件A4文件，并可将A4文件沿轨迹9移动，最后将其释放在手机3的协同窗口中。此时可确定目标文件A4文件存储在电脑上，且最终接收A4文件的设备为手机3。在多设备协同系统中，若多个设备之间采用WiFi-P2P技术进行组网，则电脑与手机3不能建立直接连接，但电脑与平板可建立直接连接，平板与手机3也可建立直接连接。此时电脑可与平板先建立数据传输通道，电脑将A4文件的文件信息发送给平板，然后平板在与手机3建立数据传输通道，平板将A4文件的文件信息转发给手机3。可选的，若多个设备之间采用自组网技术进行组网，则多设备协同系统中的所有设备可建立直接连接，此时电脑可与手机3建立直接连接，电脑可与手机3直接建立数据传输通道，电脑将A4文件的文件信息直接发送给手机3。
在一种可能实现的方式中，所述目标文件为所述M个第二设备中起始第二设备上存储的文件；所述控制将所述目标文件发送至所述N个设备中与所述释放位置匹配的设备，包括：当检测到所述第一拖拽操作的释放位置在第三设备的显示屏界面，或检测到所述第一拖拽操作的释放位置在所述第三设备在所述N个设备中其他设备上的协同窗口中，则控制所述起始第二设备将所述目标文件发送至所述第三设备。需要说明的是，当协同窗口中的目标文件在第一界面上被拖拽后，若目标文件被释放在多设备协同系统中任意一个设备的显示屏界面或该设备对应的协同窗口上时，则代表目标文件需发送给与该释放位置所匹配的设备。可选的，第三设备可为M个第二设备中的一个设备。例如，如图7E所示，图中用户在手机1的协同窗口中选中目标文件D文件，并可将D文件沿轨迹8移动，最后将其释放在手机2的协同窗口中，需要说明的是，此时手机1为所述起始第二设备，手机2为所述第三设备。同时，用户可在手机1的协同窗口中选中目标文件D文件，并可将D文件沿轨迹10移动，最后将其释放在平板的显示屏界面上，需要说明的是，此时手机1为所述起始第二设备，平板为所述第三设备。
在一种可能实现的方式中，所述控制所述起始第二设备将所述目标文件发送至所述第三设备，包括：建立数据传输通道；所述数据传输通道用于传输所述目标文件的所述文件信息；若所述起始第二设备与所述第三设备建立直接连接，则通过所述数据传输通道将所述文件信息发送到与所述释放位置匹配的设备的所述存储路径；若所述起始第二设备与所述第三设备建立间接连接，则通过所述数据传输通道将所述文件信息发送给中继设备，通过所述中继设备将所述文件信息转发给与所述释放位置匹配的设备所述存储路径，其中所述中继设备为与所述起始第二设备建立直接连接同时与所述第三设备建立直接连接的设备。在本发明实施例中，在多设备协同系统中，由于使用了不同的组网技术，从而可实现更多设备的连接同时不用断开设备间的协同。但不同的组网技术可存在不同的组网方式可导致各设备间的连接关系发生变化。当起始第二设备作为发送设备(存储目标文件的设备，如第一设备或M个第二设备中的一个)时，起始第二设备和第三设备在使用不同的组网方式下可建立直接连接也可建 立间接连接。如起始第二设备与第三设备可建立直接连接(如使用自组网技术进行组网)，则起始第二设备可将目标文件的文件信息直接发送给第三设备，如起始第二设备与第三设备未建立直接连接而是通过中继设备(如第一设备)建立了间接连接(如使用WiFi-P2P技术组网实现设备间一对多的连接)，则起始第二设备将目标文件的文件信息先发送给中继设备，中继设备在将目标文件的文件信息转发给第三设备，从而实现多台设备文件传输。例如，如图7E所示，图7E为五个设备系统中文件拖拽示意图，图中用户在手机1的协同窗口中选中目标文件D文件，并可将D文件沿轨迹8移动，最后将其释放在手机2的协同窗口中。需要说明的是，在上述例子中所述起始第二设备为手机1，所述第三设备为手机2。此时可确定目标文件D文件存储在手机1上，最终接收D文件的设备为手机2。在多设备协同系统中，若多个设备之间采用WiFi-P2P技术进行组网，则手机1与手机2不能建立直接连接，但手机1与电脑可建立直接连接，电脑与手机2也可建立直接连接。此时手机1可与电脑先建立数据传输通道，手机1将D文件的文件信息发送给电脑，然后电脑在与手机2建立数据传输通道，电脑将D文件的文件信息转发给手机2。可选的，若多个设备之间采用自组网技术进行组网，则多设备协同系统中的所有设备可建立直接连接，此时手机1可与手机2建立直接连接，手机1可与手机2直接建立数据传输通道，手机1将D文件的文件信息直接发送给手机2。
步骤S6010：第三设备接收第一设备所控制发送的所述目标文件。
具体地，当第一设备控制将所述目标文件发送至第三设备后，第三设备可将所述目标文件存储在设备中。在一种可能实现的方式中，所述接收第一设备所控制发送的所述目标文件，包括：与存储所述目标文件的设备建立数据传输通道，接收所述目标文件的文件信息，所述文件信息包括所述目标文件的文件名、文件内容、文件大小信息。需要说明的是，第三设备会接收到来自发送设备发送的目标文件的大小的信息，在判断第三设备有足够的空间接收该目标文件后，第三设备可接收到目标文件的文件信息。例如，如图7E所示，若当用户在第一界面上选中D文件并沿着轨迹8拖拽D文件，且在手机2的协同窗口中释放拖拽操作，此时手机2作为第三设备，则电脑会控制手机1将D文件发送给手机2。手机2会接收D文件并将D文件存储在本地。
步骤S6011：第三设备发送广播通知所述多设备协同系统中的其他设备所述目标文件已被成功接收。
具体地，当第三设备在成功接收了目标文件后，会发送广播通知多设备协同系统中的其他设备所述目标文件已经被成功接收，其他设备无需在等待接收。例如，如图7E所示，若当用户在第一界面上选中D文件并沿着轨迹8拖拽D文件，且在手机2的协同窗口中释放拖拽操作，此时手机2作为第三设备，则电脑会控制手机1将D文件发送给手机2。在手机2成功接收D文件后，会通知多设备协同系统中的手机1、电脑、平板和手机3，D文件已经被成功接收，无需在等待接收。
