存储模块22包括存储控制器(即Flash控制器)23及与存储控制器23相连的多个存储单元(即Flash)24，存储控制器23用于控制多个存储单元24的读写。具体的，存储控制器23中有控制芯片，以实现控制存储单元的读写、磨损均衡、寿命监控等功能。
存储装置20还包括处理器25，处理器25与格式转换模块21及存储控制器23通信连接，处理器25用于读取存储装置20接收的指令信号；具体的，处理器25读取存储装置20接收的指令信号后，产生相应的操作控制信号，并发送至格式转换模块21及存储控制器23，从而控制格式转换模块21及存储控制器23按照指令信号的要求进行动作，处理器25还用于判断文件的初始格式与目标格式是否一致。所述指令信号可以为上传指令(即上传终端30请求上传文件对应的指令信号)或访问指令(即访问终端40请求访问上传的文件对应的指令信号，所述操作控制信号可以为存储指令、转换指令或删除指令。
例如，上传终端30将上传指令发送至主机10，主机10接收上传指令并将上传指令传送至存储装置20，处理器25读取上传指令并判断上传的文件的初始格式与目标格式是否一致，若上传的文件的初始格式与目标格式一致，则处理器25发送存储指令至存储模块22，存储模块22内的存储控制器23接收存储指令，并将上传的文件存储至存储单元24内；若上传的文件的初始格式与目标格式不一致，则处理器25发送转换指令至格式转 换模块21，格式转换模块21接收转换指令并将上传文件的初始格式转换为目标格式，再发送存储指令至存储模块22，存储模块22内的存储控制器23接收存储指令，并将转换后的目标格式的文件存储至存储单元24内。
进一步地，所述上传指令可以包括期限设置信息，当上传终端30将文件上传(即上传的文件存储在存储单元24内)后，上传终端30响应用户的期限设置操作为上传的文件设置访问期限。处理器25读取上传指令并分析该上传指令对应的期限设置信息，当存储单元24内的文件的存储时间达到用户设置的访问期限时，处理器25发送删除指令至存储控制器23，存储控制器23接收删除指令将存储单元24内的文件删除。期限设置信息可以为三天可见、半年可见或一年可见，即当上传文件的用户为上传的文件设置访问期限后，上传的文件在访问期限内可见，当上传的文件的存储时间达到或超出访问期限后，上传的文件已被删除且不可见，节省了存储单元24的存储空间。
进一步地，所述上传指令还可以包括权限设置信息，当上传终端30请求上传文件时，上传终端30响应用户的权限设置操作为上传的文件设置访问权限，具体的，权限设置信息可以为仅自己可见、全部可见或部分可见。处理器25读取上传指令并分析该上传指令对应的权限设置信息，若权限设置信息为仅自己可见，则处理器25直接发送存储指令至存储模块22，存储模块22内的存储控制器23接收存储指令，并将上传的文件存储至存储单元24内；若权限设置信息为全部可见，则处理器25发送转换指令至格式转换模块21，格式转换模块21接收转换指令并将上传文件的初始格式转换为目标格式，再发送存储指令至存储模块22，存储模块22内的存储控制器23接收存储指令，并将转换后的目标格式的文件存储至存储单元24内，此时，目标格式即为当前各类终端较为通用的文件格式；若权限设置信息为部分可见，则处理器25发送转换指令至格式转换模块21，格式转换模块21接收转换指令并将上传文件的初始格式转换为目标格式，再发送存储指令至存储模块22，存储模块22内的存储控制器23接收存储指令，并将转换后的目标格式的文件存储至存储单元24内，此时，目标格式即为用户设置的部分可见的终端的类型所对应的文件格式，可以理解，用户设 置的部分可见的终端的类型可以根据上传终端30的历史使用数据进行确定。
存储装置20还包括总线接口26，总线接口26与处理器25及格式转换模块21通信连接；总线接口26用于连接主机10，并进行指令信号传送。例如，上传终端30将上传文件所对应的上传指令发送至主机10，主机10接收上传指令，且主机10将上传指令通过总线接口26传送至存储装置20；或者，当访问用户需要访问文件存储系统100内的文件时，访问终端将访问指令发送至主机10，主机10接收访问指令，且主机10将访问指令通过总线接口26传送至存储装置20，存储装置20根据访问指令从存储模块22中调出与访问终端类型匹配的目标格式的文件，并将目标格式文件通过总线接口26发送至主机10。如此，总线接口26实现了存储装置20及主机10之间的上传指令及访问指令的信号传送。
本发明较佳实施例提供的文件存储系统100，具体的，当访问用户需要访问文件存储系统100内的文件时，主机10接收访问终端40发送的访问指令求并将访问指令发送至存储装置20；存储装置20根据访问指令从存储模块22中调出与访问终端40类型匹配的目标格式的文件，并将目标格式文件发送至主机10；主机10将目标格式文件发送至访问终端40。如此，便实现了通过文件存储系统100，实现了上传终端30与访问终端40之间的文件共享，并且，文件存储系统100在存储装置20内进行文件的格式转换及存储，能够直接反馈与访问终端匹配的目标格式文件。访问终端40可以为手机、电脑、PAD(平板电脑)、数码相机等移动终端中的一种或多种。
具体的，当存储模块22中未存储与访问终端40类型匹配的目标格式的文件时，格式转换模块21将访问终端40请求访问的文件的格式转换为与访问终端40类型匹配的目标格式的文件，并将目标格式的文件发送给所述主机10。本实施方式中，若存储模块22中未存储与访问终端40类型匹配的目标格式的文件，即与访问终端40所匹配的文件格式为非通用格式文件，存储装置20对该文件进行格式转换后而不进行存储，即存储模块22内不存储非通用格式的文件，以减少对存储模块22的空间的占用；在其他 实施方式中，也可以将转换后的非通用格式的文件存储在存储模块22中，以根据后续访问用户的请求访问指令直接调出目标格式的文件，减少对存储装置20的处理器25的资源占用。
本发明较佳实施例提供的文件存储系统100，当访问用户在访问终端40上浏览文件时，首先是顺序翻看文件，此时，主机10就只反馈占用空间较小的缩略文件，即主机10将目标格式文件对应的缩略文件发送至访问终端40，访问终端40顺序显示缩略文件；而当访问用户对某个文件感兴趣并点击感兴趣的文件时，则主机反馈占用空间较大但更为清晰的文件，即当访问终端40接收到访问用户的点击指令时，访问终端40将点击指令传送至主机10，主机10根据点击指令将缩略文件对应的目标格式文件并发送至访问终端40，访问终端40显示目标格式文件。如此，可大大的节省访问终端40的资源占用。
本发明较佳实施例提供的文件存储系统100，在存储装置20内，格式转换模块21将文件的初始格式转换为目标格式，并将目标格式的文件存储至存储装置20本地的存储模块22内，实现了在存储装置20内进行文件的格式转换及存储，文件的格式转换未占用主机10的资源，并且，避免了转换后的目标格式的文件需要从主机10传输到存储装置20，节省了主机10与存储装置20间的总线能量。
请参阅图2，图2为本发明较佳实施例提供的文件存储方法的流程图；需要说明的是，本发明的方法并不受限于下述步骤的顺序，且其他实施例中，本发明的方法可以只包括以下步骤的其中一部分，或者其中一个步骤可以被拆分为几个步骤，或者多个步骤也可以合并为一个步骤。本发明较佳实施例提供的文件存储方法包括如下步骤：
步骤S10：主机接收上传终端发送的文件，并将文件传送至存储装置。
步骤S20：存储装置内的格式转换模块将文件的初始格式转换为目标格式。

本发明较佳实施例提供的文件存储方法，实现了在存储装置20内进行文件的格式转换及存储，文件的格式转换未占用主机10的资源，并且，避 免了转换后的目标格式的文件需要从主机10传输到存储装置20，节省了主机10与存储装置20间的总线能量。
本实施例中的文件存储方法的具体描述可参考上述实施例中对文件存储系统100的描述，在此不再赘述。
本发明较佳实施例提供的文件存储方法，具体的，在步骤S20中，存储装置内的处理器判断上传的文件的初始格式与目标格式是否一致，若上传的文件的初始格式与目标格式一致，则处理器控制存储模块存储上传的文件；若上传的文件的初始格式与目标格式不一致，则处理器控制格式转换模块将上传文件的初始格式转换为目标格式后，再将转换后的目标格式的文件存储至存储模块内。
在其他实施方式中，为了节省存储模块的存储空间，步骤S20还包括如下步骤：
处理器读取存储装置接收的上传指令并分析上传指令对应的期限设置信息；
当存储模块内的文件的存储时间达到用户设置的访问期限时，处理器发送删除指令至存储模块内的存储控制器；
