摘　　要：针对大文件在网络存储过程中可能存在的上传和下载失败问题,提出了一种利用数据库进行分块存储和管理较大文件的方法。将一个较大的文件分割成多块,分别对分割后的每一块进行上传或下载,从而避免了网络因素对直接上传和下载较大文件所产生的影响。测试表明,通过所提出的分块与合并方法,可以有效地避免文件上传和下载过程中可能出现的失败问题,提高了上传和下载的效率。To solve the failure problem of the network storage process while uploading and downloading large files, this paper puts forward a method to store and manage large files in blocks by database. Split a large file into some blocks and then upload or download them separately, that can avoid the influence of the network factors on directly uploading and downloading large files. Tests show that, the method proposed in the paper can effectively avoid the failures that may exist in the file uploading and down loading process, and improve the efficiency of uploading and downloading large files.
