正确答案及解析
正确答案
解析
Windows操作系统中的文件目录结构：
在对数据文件进行操作时，一般要用盘符指出被操作的文件或目录在哪一磁盘。盘符也称驱动器名。
文件是按一定格式建立在外存储介质上的一组相关信息的集合。计算机中的文件，一般上存储在磁盘、光盘或磁带中，如果没有特殊说明，我们认为文件上存储在磁盘上的，称为磁盘文件。每一个文件必须有一个名字，称为文件名。
文件目录，即Windows操作系统中的文件夹。为了实现对文件的统一管理，同时又方便用户，操作系统采用树状结构的目录来实现对磁盘上所有文件的组织和管理。根目录用“＼”表示，从根目录或当前目录至所要找的文件或目录所需要经过的全部子目录的顺序组合。
绝对路径指的是从根目录开始到目标文件或目录的一条路径。所以fl．java文件的绝对路径是“D：＼Program＼java-prog＼f1. dava”。
