Description

一种电子设备的数据操作方法及电子设备 技术领域
本发明涉及存储技术领域，尤其涉及一种电子设备的数据操作方法及电子设备。
背景技术
随着电子设备的智能化发展，电子设备中有限的内部存储空间已无法完全满足用户的需求，因此，越来越多的电子设备开始支持外部存储空间的扩展如安全数字(Secure Digital，SD)卡扩展等。若电子设备中只存在内部存储空间，系统的默认存储空间为内部存储空间，若用户经电子设备进行了外部存储空间的扩展如插入了一个或多个SD卡，则系统会要求用户预先设置一个存储空间作为默认存储空间或根据出厂设置时将内部存储空间作为默认存储空间。电子设备在使用一段时间之后，可能会存在默认存储器的存储空间已满而非默认存储器的存储空间存在较大剩余的情况，此时用户需分别查看各个存储空间的剩余空间存储容量后通过手动设置当前数据的存储位置才能实现存储资源的分配。同时，在进行数据读取时用户也需要分别查看不同的存储空间来查询数据的存储位置，不仅浪费了电子设备的存储资源，也给用户带来了极大的不便。
发明内容
本发明实施例提供了一种电子设备的数据操作方法及电子设备，以期提高电子设备的存储资源利用率以及数据操作的便捷性。

若不满足，从与电子设备已进行通信连接的至少一个存储设备中选择目标存储设备，并将目标迁移数据迁移至目标存储设备中，目标迁移数据为已写入电子设备中的部分或全部数据。
上述技术方案中，在目标写入数据的占用空间量不满足电子设备的存储空间的存储要求，可以通过自动进行数据迁移来释放存储空间，以供目标写入数据的写入，有利于电子设备存储空间的灵活管理，提高了电子设备的存储资源利用率。
结合第一方面和第一方面的第一、二、三、四种可能的实施方式，在第一方面的第五种可能的实施方式中，还包括：

具体实施方式
为使得本发明的发明目的、特征、优点能够更加的明显和易懂，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例中，所述电子设备可以包括用户终端如手机、电脑、移动互联网设备(Mobile Internet Device，MID)等或服务器以及其它支持外部存储空间扩展如SD卡扩展的电子设备。
请参见图1，图1为本发明的一个实施例提供的一种电子设备的数据操作方法的流程示意图。如图1所示，本发明的一个实施例提供的一种电子设备的数据操作方法可包括步骤S101～S103。
S101、接收数据写入指令，所述数据写入指令携带目标写入数据。
具体的，电子设备接收数据写入指令，所述数据写入指令携带目标写入数据。本发明实施例中，所述电子设备中可以包括一个内部物理存储器和至少一个外部物理存储器。用户可以通过电子设备的输入装置例如触屏装置输入目标写入数据，或从其它电子设备上将目标写入数据发送给所述电子设备。用户触发数据写入操作后，所述电子设备会接收到数据写入指令，所述数据写入指令携带有目标写入数据，所述目标写入数据可以是字符信息，也可以是音视频文件或文本文档等等。用户在触发数据写入操作时，可以选择相应的存储位置，若用户直接手动选择内部存储空间或者是外部存储空间如SD卡存储，则所述电子设备无需进行存储空间的自动选择，直接将目标写入数据直接写入至内部存储或外部存储空间中；若用户选择“系统自动选择”存储空间，则可以由系统根据预设规则进行自动选择，执行步骤S102和S103。
S102、根据预设规则选择所述所有存储空间中的至少一个作为目标存储空间，并在所述目标存储空间执行写入操作。
具体的，所述电子设备可以根据预设规则选择所述所有存储空间中的至少一个作为目标存储空间，并在所述目标存储空间执行写入操作。当用户确定由系统自动选择时，则电子设备可以在接收到数据写入指令后，根据预设规则自动选择目标存储空间，所述预设规则可以是根据目标写入数据的地点、安全级别、类型、占用空间量等至少一个条件选择目标存储空间，例如，目标写入数据为密码信息，安全级别较高，因此可以通过判断目标写入数据的安全级别较高确定将所述密码信息写入内部存储空间中；又如，目标写入数据为视频文件，占用空间量相对较大，为了避免电子设备因内存被占用较多而影响其系统运行速度，可将占用空间量相对较大的视频文件存储于外部存储空间中。
S103、在写入操作完成后，更新虚拟存储卡中存储的所述电子设备的所有存储空间中相同文件类型的文件汇总融合后的虚拟文件，并更新所述虚拟存储卡对应的虚拟存储路径和所述目标存储空间对应的物理存储路径之间的映射关系。
具体的，所述电子设备在写入操作完成后，更新虚拟存储卡中存储的所述电子设备的所有存储空间中相同文件类型的文件汇总融合后的虚拟文件，并更新所述虚拟存储卡对应的虚拟存储路径和所述目标存储空间对应的物理存储路径之间的映射关系。本发明实施例中，为了保证电子设备能够对存储空间进行统一管 理，可以采用在电子设备中增加虚拟存储卡的方式，例如可以在手机操作系统的文件系统中增加一个“虚拟存储卡”的文件结构，其存储内容的实际路径为电子设备的内部存储空间和/或外部存储空间，存储内容可以包括内部存储卡的文件结构和外部SD存储卡的文件结构融合后的虚拟文件。在所述目标写入数据存储于目标存储空间之后，可以更新虚拟存储卡中存储的所述电子设备的所有存储空间中相同文件类型的文件汇总融合后的虚拟文件，例如若目标写入数据为视频文件，已写入至SD1卡中，则可以将目标写入数据汇总至视频类的虚拟文件中，并更新所述虚拟文件对应的虚拟存储路径与SD1卡之间的映射关系。
由上可见，本发明实施例可以通过接收数据写入指令，然后根据预设规则选择所述所有存储空间中的至少一个作为目标存储空间，并在所述目标存储空间执行写入操作，在写入操作完成后，更新虚拟存储卡中存储的所述电子设备的所有存储空间中相同文件类型的文件汇总融合后的虚拟文件，并更新所述虚拟存储卡对应的虚拟存储路径和所述目标存储空间对应的物理存储路径之间的映射关系，本发明实施例通过预设规则自动获取合适的目标存储空间，提高了电子设备存储的便捷性，并采用虚拟存储卡的方式实现对存储空间的统一管理和分配，有利于提高电子设备的存储资源利用率。
请参见图2，图2为本发明的一个实施例提供的另一种电子设备的数据操作方法的流程示意图。如图2所示，本发明的一个实施例提供的另一种电子设备的数据操作方法，可包括步骤S201～S206。
S201、接收数据写入指令，所述数据写入指令携带目标写入数据。
具体的，电子设备接收数据写入指令，所述数据写入指令携带目标写入数据。本发明实施例中，所述电子设备中可以包括一个内部物理存储器和至少一个外部物理存储器。用户可以通过电子设备的输入装置例如触屏装置输入目标写入数据，或从其它电子设备上将目标写入数据发送给所述电子设备。用户触发数据写入操作后，所述电子设备会接收到数据写入指令，所述数据写入指令携带有目标写入数据，所述目标写入数据可以是字符信息，也可以是音视频文件或文本文档等等。用户在触发数据写入操作时，可以选择相应的存储位置，若用户直接手动选择内部存储空间或者是外部存储空间如SD卡存储，则所述电子设备无需进行 存储空间的自动选择，直接将目标写入数据直接写入至内部存储或外部存储空间中；若用户选择“系统自动选择”存储空间，则可以由系统根据预设规则进行自动选择，则可以执行本发明实施例中的其它步骤。
S202、判断所述目标写入数据的占用空间量是否满足所述电子设备的存储空间的存储要求。
具体的，所述电子设备判断所述目标写入数据的占用空间量是否满足所述电子设备的存储空间的存储要求。本发明实施例中，为了保证电子设备能够对存储空间进行统一管理，可以采用在电子设备中增加虚拟存储卡的方式，例如可以在手机操作系统的文件系统中增加一个“虚拟存储卡”的文件结构，其存储内容的实际路径为电子设备的内部存储空间和/或外部存储空间，存储内容可以包括内部存储卡的文件结构和外部SD存储卡的文件结构融合后的虚拟文件。当用户采用系统自动选择存储空间时，可以获取到虚拟存储卡的总存储空间量和总剩余空间量，若所述电子设备的存储空间的存储要求为在写入目标写入数据之后，所述电子设备判断存储空间的总剩余空间量是否大于预设阈值例如10％，并可以根据判断结果确定是否需要进行存储空间中的数据迁移。若在写入目标写入数据之后，所述电子设备判断存储空间的总剩余空间量大于预设阈值，则说明所述目标写入数据可以直接进行写入，执行步骤S204，否则，需要先进行数据迁移之后再进行目标写入数据的写入操作，可执行步骤S203。
S203、若所述目标写入数据的占用空间量不满足所述电子设备的存储空间的存储要求，从与所述电子设备已进行通信连接的至少一个存储设备中选择目标存储设备，并将目标迁移数据迁移至所述目标存储设备中，所述目标迁移数据为已写入所述电子设备中的部分或全部数据。
具体的，若所述目标写入数据的占用空间量不满足所述电子设备的存储空间的存储要求，所述电子设备可以从与所述电子设备已进行通信连接的至少一个存储设备中选择目标存储设备，并将目标迁移数据迁移至所述目标存储设备中，所述目标迁移数据为已写入所述电子设备中的部分或全部数据。本发明实施例中，若所述目标写入数据的占用空间量不满足所述电子设备的存储空间的存储要求，则说明所述电子设备中的剩余存储空间无法满足所述目标写入数据的写入，因此需要通过将电子设备中的部分已写入的存储空间进行释放。例如可以在电子设备 进行联网的情况下，通过将所述电子设备中的部分或全部数据上传至云端。又如可以将所述电子设备通过WIFI热点与其它存储设备相连，然后按照预设迁移规则将所述电子设备中的存储数据迁移至其它的存储设备中。其中，预设迁移规则可以是将电子设备中的照片按照存储时间在先的先传的规则迁移至其它的存储设备，直到迁移数据的大小满足预设的要求或迁移数据之后的电子设备的剩余存储空间能够满足所述目标写入数据的存储要求。
S204、若所述目标写入数据的占用空间量满足所述电子设备的存储空间的存储要求，根据预设规则选择所述所有存储空间中的至少一个作为目标存储空间。
具体的，若所述目标写入数据的占用空间量满足所述电子设备的存储空间的存储要求，所述电子设备根据预设规则选择所述所有存储空间中的至少一个作为目标存储空间。本发明实施例中，若所述目标写入数据的占用空间量满足所述电子设备的存储空间的存储要求，可以根据预设规则自动选择目标存储空间。其中，预设规则可以是根据目标写入数据的地点、安全级别、类型、占用空间量等至少一个条件选择目标存储空间。例如，目标写入数据为密码信息，安全级别较高，因此可以通过判断目标写入数据的安全级别较高确定将所述密码信息写入内部存储空间中。又如，目标写入数据为视频文件，占用空间量相对较大，为了避免电子设备因内存被占用较多而影响其系统运行速度，因此可将占用空间量相对较大的视频文件存储于外部存储空间中。
可选的，若所述目标写入数据的安全级别满足预设安全阈值，选择所述内部存储空间作为目标存储空间，否则，选择所述至少一个外部存储空间作为目标存储空间。
在本发明实施例中，所述电子设备可以通过目标写入数据的安全级别来选择目标存储空间，例如目标写入数据为密码，其安全级别较高，由于内部存储更安全稳定可靠，因此可以选择内部存储空间为目标存储空间。又如，目标写入数据为缓存数据，安全级别较低，因此可以选择所述至少一个外部存储空间作为目标存储空间。可选的，上述对于目标存储空间的选择不局限于上述预设规则，也可以将其中一个外部存储空间指定为在安全级别较高时选择的目标存储空间。
可选的，若所述目标写入数据的占用空间量满足预设空间阈值，选择所述至 少一个外部存储空间作为目标存储空间，否则，选择所述内部存储空间作为目标存储空间。
在本发明实施例中，为了避免电子设备系统的顺畅运行，可以在预设规则中设置将占用空间量较大的目标写入数据写入至外部存储空间而非内部存储空间，例如，目标写入数据的占用空间量为300M，超过了预设空间阈值200M，则可以根据预设规则选择其中一个外部存储空间作为目标存储空间。
可选的，若所述目标写入数据为可分离数据且占用空间量大于任意一个存储空间，选择所述内部空间和/或所述至少一个外部空间作为目标存储空间。
本发明实施例中，在所述目标写入数据占用空间量较大的情况下，或者是当任意一个存储空间无法存储目标写入数据，而总剩余空间存储容量能够满足于目标写入数据写入的情况下，可以判断所述目标写入数据是否为可分离数据，即可以一部分存储于内部存储空间中，另一部分存储于外部存储空间中，例如，当所述目标写入数据为包含文本文档和视频文件，可以根据各个存储空间的剩余空间存储容量的情况选择将文本文档和视频文件分别存储于内部存储空间和外部存储空间中，也可以是存储于两个不同的外部存储空间中。
可选的，若所述目标写入数据的存储地点为安全存储区域，选择所述至少一个外部存储空间作为目标存储空间，否则，选择所述内部存储空间作为目标存储空间。
本发明实施例中，假设用户携带电子设备在私人场所存储目标写入数据，可以选择至少一个外部空间作为目标存储空间，而如果在公共场所，则可以将当前的目标写入数据直接写入系统内存中。
上述可选的任意步骤可替换S204，也可以一个或多个步骤相结合进行选择，例如可以根据所述目标写入数据的安全级别和存储区域，来确定目标存储空间。
S205、在所述目标存储空间执行写入操作。
S206、在写入操作完成后，更新虚拟存储卡中存储的所述电子设备的所有存储空间中相同文件类型的文件汇总融合后的虚拟文件，并更新所述虚拟存储卡对应的虚拟存储路径和所述目标存储空间对应的物理存储路径之间的映射关系。
步骤S206的详细解释请参考图1实施例中的步骤S103的具体解释，在此不再赘述。
进一步可选的，若检测到新增的第一个外部存储空间，生成虚拟存储卡以及所述虚拟存储卡中存储的所述外部存储空间和所述电子设备的内部存储空间中相同文件类型的文件汇总融合后的虚拟文件，并建立所述虚拟存储卡对应的虚拟存储路径和所述目标存储空间对应的物理存储路径之间的映射关系。
电子设备初始时只存在内部存储空间，当用户首次将SD卡插入所述电子设备中之后，所述电子设备可以检测到新增的第一个外部存储空间，并生成虚拟存储卡。新增的SD卡和内部存储空间中相同文件类型的文件如视频、音频、文档等可以进行汇总融合，形成多个虚拟文件，并可以分别建立所述虚拟存储卡对应的虚拟存储路径和所述目标存储空间对应的物理存储路径之间的映射关系，例如可以建立虚拟存储卡中的视频存储路径与SD1卡对应的物理存储路径之间的映射关系。
进一步可选的，若检测到新增的至少一个外部存储空间且所述至少一个外部存储空间为非第一个外部存储空间，更新虚拟存储卡中存储的所述增加的至少一个外部存储空间和所述所有存储空间中相同文件类型的文件汇总融合后的虚拟文件，并更新所述虚拟存储卡对应的虚拟存储路径和所述新增至少一个外部存储空间对应的物理存储路径之间的映射关系。
电子设备已存在内部存储空间和外部存储空间，用户增加新的外部存储空间如将SD2卡插入所述电子设备中之后，虚拟存储卡中源虚拟文件需要结合新的外部存储空间中的存储文件进行更新，例如SD2卡中有300M的视频文件，则可以将原来的虚拟视频文件总占用空间量增加300M，并将虚拟存储卡中的总存储容量增加300M，并可以建立虚拟存储卡中存储视频的虚拟存储路径与SD2卡对应的物理存储路径之间的映射关系。
进一步可选的，若检测到所述至少一个外部存储空间中的任意一个被移除，根据所述被移除的至少一个外部存储空间更新虚拟存储卡中存储的所述所有存储空间中相同文件类型的文件汇总融合后的虚拟文件；解除所述虚拟存储卡对应的虚拟存储路径和所述移除的至少一个外部存储空间对应的物理存储路径之间的映射关系。
若电子设备中存在内部存储空间以及SD1卡和SD2卡两个外部存储空间，若用户拔出了SD1卡，则电子设备检测到SD1卡被移除后，可以在虚拟存储卡中存 储的虚拟文件中删除SD卡的相关信息，如SD1卡容量为1G中存储有100M的文档信息内容，则可以将虚拟存储卡的总存储容量减少1G，并将剩余空间存储容量减少900M，然后将虚拟文档文件的总存储容量减少100M。然后可以解除SD1卡对应的物理存储路径与虚拟存储卡的虚拟存储路径之间的映射关系。
进一步可选的，若检测到计算机连接信号，向所述计算机发送所述虚拟存储卡的驱动文件并指示所述计算机安装所述驱动文件以使所述计算机显示所述虚拟存储卡的存储信息。
检测到电子设备通过USB接口等方式连接到计算机中，电子设备可以自动向所述计算机发送虚拟存储卡的驱动文件，以使计算机自动安装所述驱动文件，当驱动文件安装成功之后，计算机界面上可以显示出“虚拟存储卡”图标，打开后可以看到虚拟存储卡对应的响应虚拟文件，从而使用户能够方便地执行文件的拷入、拷出以及其它的文件管理操作。
进一步可选的，接收数据读取指令，所述数据读取指令中携带目标读取数据对应的目标虚拟存储路径；确定所述目标虚拟存储路径映射的目标物理存储路径；通过所述目标物理存储路径读取所述目标读取数据。
用户设备接收到数据读取指令，可以根据所述数据读取指令获得需要读取的目标读取数据对应的目标虚拟存储路径，例如用户点击进入“虚拟存储卡”并进一步点击视频图标，该索引目录为目标虚拟存储路径，然后可以根据所述目标虚拟存储路径获得物理存储路径，即从内部存储空间或外部存储空间中读取所述目标读取数据。
进一步可选的，接收数据删除指令，所述数据删除指令中携带目标删除数据对应的目标虚拟存储路径；确定所述目标虚拟存储路径映射的目标物理存储路径；通过所述目标物理存储路径删除所述目标删除数据。
用户设备接收到数据删除指令，可以根据所述数据删除指令获得需要删除的目标删除数据对应的目标虚拟存储路径，然后获得物理存储路径，并将该内部存储空间或外部存储空间中存储的所述目标读取数据进行删除。
可以看出，本发明实施例可以通过接收数据写入指令，然后所述目标写入数据的占用空间量是否满足所述电子设备的存储空间的存储要求，确定是否按照预设规则进行目标存储空间选择，或先进行数据迁移再进行目标存储空间选择，在 写入操作完成之后，更新虚拟存储卡中存储的虚拟文件以及虚拟存储卡对应的虚拟存储路径和所述目标存储空间对应的物理存储路径之间的映射关系，通过目标存储空间的自动选择，并通过数据迁移调整剩余空间存储容量，提高了电子设备的便捷性和灵活性，采用虚拟存储卡的方式实现对存储空间的统一管理和分配，有利于提高电子设备的存储资源利用率。

具体的，当用户欲对所述电子设备的存储信息进行查询操作时，首先可以通过点击存储位置设置界面来选择相应的存储位置，如图3a中的界面包括三个按钮：内部存储11、SD卡12和系统自动选择13，若用户直接手动选择内部存储11或者是SD卡12，则所述电子设备无需进行存储空间的自动选择，可根据选择将目标写入数据直接写入至内部存储空间或外部存储空间中。当用户点击内部存储11或SD卡12，则可以弹出如图3b所示的内部存储空间和外部存储空间存储界面，该界面的内部存储空间界面和外部存储空间存储界面为独立的界面，可以单独弹出，其中，内部存储空间可以将存储的文件划分成应用程序类，图片视频类，音乐、铃声、播客等类，下载内容类，缓存数据类以及其他类等进行显示，SD卡存储可以显示总存储空间量和剩余存储空间量，也可以将存储的文件进行类别划分后显示。
若用户点击如图3a中的系统自动选择13，则可以由系统根据预设规则进行自动选择，可显示出图3c所示的界面，所述3c为虚拟存储卡界面示意图，其中，虚拟存储卡图标14包含内部存储空间和外部存储空间的总存储空间15和总剩余存储空间16，点击虚拟存储卡的图标可进一步对存储情况进行查询，可弹出如图3d所示的虚拟存储卡的分类存储界面，该界面中可以将电子设备中所有存储空间， 包括内部存储空间和外部存储空间的文件进行汇总融合生成虚拟文件，可显示出应用程序类，图片视频类等多个类别的存储信息。
可选的，用户执行对第一个外部存储空间的增加操作被检测到；响应于检测到所述空间增加操作，虚拟存储卡对应的虚拟存储路径与所述所有存储空间对应的物理存储路径的映射关系被建立，且所述虚拟存储卡上的存储信息被显示；其中，所述虚拟存储卡上的存储信息包括所述第一个外部存储空间和所述电子设备的内部存储空间中相同文件类型的文件汇总融合后的虚拟文件。
电子设备在初始时只存在内部存储空间，当用户第一次扩展外部存储空间如插入一个SD卡时，电子设备会检测到外部存储空间的增加操作，并可响应该空间增加操作，虚拟存储卡对应的虚拟存储路径与所述所有存储空间对应的物理存储路径的映射关系会被建立，原有的内部存储空间的存储信息将不再显示，图形用户界面会生成一个虚拟存储卡的图标并显示，如图3c所示的界面，进一步点击虚拟存储卡图标，可以显示出该虚拟存储卡的存储信息，其中，该虚拟存储卡的存储信息包括内部存储空间和新增的SD卡的所有文件汇总融合后的虚拟文件，如图3d所示的界面。
可选的，用户执行对至少一个外部存储空间的移除操作被检测到；响应于检测到所述空间移除操作，虚拟存储卡对应的虚拟存储路径与所述所有存储空间对应的物理存储路径的映射关系被更新，且所述虚拟存储卡上更新的存储信息被显示；其中，所述虚拟存储卡上更新的存储信息包括所述电子设备的所有存储空间中除所述移除的至少一个外部存储空间的存储空间中相同文件类型的文件汇总融合后的虚拟文件。
当用户移除一个SD卡时，电子设备会检测到外部存储空间的移除操作，并可响应该空间移除操作，虚拟存储卡对应的虚拟存储路径与所述所有存储空间对应的物理存储路径的映射关系会被更新，原有的虚拟存储文件将被更新显示，如图3c所示的界面中的总存储空间量和剩余存储空间量将会根据被移除的SD卡的存储空间以及存储于原SD卡上的文件的占用空间量进行调整。进一步点击虚拟存储卡图标后，可以显示出更新后的虚拟存储卡的存储信息。
本发明实施例采用“虚拟存储卡”的图形用户界面，可以方便与用户对存储信息进行读写、查询和存储空间的管理，将多个存储空间的存储信息进行汇总融 合，便于用户读取。
