Abstract
一种大文件自动分解的方法以及分解系统,属于电脑软件领域,所述方法包括:记录文件分解大小阈值(S100);当文件新建或者文件有更新时,检测文件大小(S101);当所述文件大小大于所述文件分解大小阈值时,分解文件(S102)。通过预设文件分解大小阈值,当文件新建或者文件有更新时,文件大小大于文件分解大小阈值时,自动分解文件,避免因为单个文件过大导致文件打开缓慢及文件功能使用效率差的情况。
Description
本发明属于电脑软件领域,提供了一种大文件自动分解的方法以及分解系统。
文件系统是操作系统用于明确存储设备(常见的是磁盘,也有基于NAND
Flash的固态硬盘)或分区上的文件的方法和数据结构;即在存储设备上组织文件的方法。操作系统中负责管理和存储文件信息的软件机构称为文件管理系统,简称文件系统。文件系统由三部分组成:文件系统的接口,对对象操纵和管理的软件集合,对象及属性。从系统角度来看,文件系统是对文件存储设备的空间进行组织和分配,负责文件存储并对存入的文件进行保护和检索的系统。具体地说,它负责为用户建立文件,存入、读出、修改、转储文件,控制文件的存取,当用户不再使用时撤销文件等。
计算机文件(或称文件、电脑档案、档案),是存储在某种长期储存设备上的一段数据流。所谓'长期储存设备'一般指磁盘、光盘、磁带等。其特点是所存信息可以长期、多次使用,不会因为断电而消失。
用户在使用电脑打开文档需要查看时,特别是某些软件自动生成日志文档,工作上的文档。这些文档通常会很大,有些有几十Mb,上百Mb,甚至是几G。在打开时,用户需要等待很长时间,等文档全部打开后,用户使用查看,搜索文档内容等功能时,由于内存限制,也会造成使用缓慢等问题。
综上,需要针对用户使用电脑操作大文件时效率低的情况,提供一种通过预设文件分解大小阈值,当文件新建或者文件有更新时,文件大小大于文件分解大小阈值时,自动分解文件,避免因为单个文件过大导致文件打开缓慢及文件功能使用效率差的情况。
本发明实施例提供了一种大文件自动分解的方法,目的在于针对用户使用电脑操作大文件时效率低的情况,提供一种通过预设文件分解大小阈值,当文件新建或者文件有更新时,文件大小大于文件分解大小阈值时,自动分解文件,避免因为单个文件过大导致文件打开缓慢及文件功能使用效率差的情况。
本发明是这样实现的:一种大文件自动分解的方法,包括以下步骤:
记录文件分解大小阈值;
当文件新建或者文件有更新时,检测文件大小;
当所述文件大小大于所述文件分解大小阈值时,分解文件。
本发明实施例还提供了一种分解系统,包括:
记录单元,读取单元,分解单元,其中:
记录单元,用于记录文件分解大小阈值;
检测单元,用于当文件新建或者文件有更新时,检测文件大小;
分解单元,其输入端分别与所述记录单元及所述检测单元的输出端连接,用于当所述文件大小大于所述文件分解大小阈值时,分解文件。
本发明通过预设文件分解大小阈值,当文件新建或者文件有更新时,文件大小大于文件分解大小阈值时,自动分解文件,避免因为单个文件过大导致文件打开缓慢及文件功能使用效率差的情况。
图1 是本发明实施例提供的一种大文件自动分解的方法的流程示意图;
图2 是本发明实施例提供的分解系统的结构示意图。
为了使本发明的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
图1是发明实施例提供的一种大文件自动分解的方法的流程示意图,为了便于说明,只示出了与本发明实施例相关的部分。
在步骤S100中,记录文件分解大小阈值。
在本实用例中,设置文件分解大小为10Mb。
在步骤S101中,当文件新建或者文件有更新时,检测文件大小。
在步骤S102中,当所述文件大小大于所述文件分解大小阈值时,分解文件。
该技术为现有技术,可以通过文档进行分割,被分割文件包括文本文件,视频文件等,但图片等文件不适合分割。例如某txt文本文档大小为30Mb,将本分割为3个文档。
本发明通过预设文件分解大小阈值,当文件新建或者文件有更新时,文件大小大于文件分解大小阈值时,自动分解文件,避免因为单个文件过大导致文件打开缓慢及文件功能使用效率差的情况。
图2是本发明实施例提供的分解系统的结构示意图,该分解系统包括:
记录单元21,读取单元22,分解单元23,其中:
记录单元21,用于记录文件分解大小阈值;
检测单元22,用于当文件新建或者文件有更新时,检测文件大小;
分解单元23,其输入端分别与所述记录单元21及所述检测单元22的输出端连接,用于当所述文件大小大于所述文件分解大小阈值时,分解文件。
其工作原理是:记录单元21,记录文件分解大小阈值,检测单元22,当文件新建或者文件有更新时,检测文件大小,分解单元23,当所述文件大小大于所述文件分解大小阈值时,分解文件。
本发明通过预设文件分解大小阈值,当文件新建或者文件有更新时,文件大小大于文件分解大小阈值时,自动分解文件,避免因为单个文件过大导致文件打开缓慢及文件功能使用效率差的情况。
以上仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本发明的保护范围之内。
