File Structure
A file is a collection of information,such as text for a memo or report, an accumulation of sales figures,or object code created by a compiler.Each file is stored under a unique name,usually on a disk storage device.The UNIX file-system provides a structure where files are arranged under directories,and directories in turn are arranged under other directories,and so forth,in a treelike organization.This structure assists users in keeping track of large numbers of files by enabling them to group related files into directories[4].Each user has one primary directory and as many subdirectories as required.
文件结构
文件是信息的汇集,如备忘录或报告的文本,累计的销售数字,或由编译程序生成的目标代码。每个文件存储在惟一名称下,通常存放在磁盘存储器上。
UNIX文件系统提供一种将文件安排在多个目录下的结构,并且这些目录又转而安排在其他目录下等这种树形组织中。这种结构帮助用户通过将相关文件分组到目录中而保有大量的文件。每一用户有一个主目录,需要时可以有多个子目录。 |
