如果扩展命令名被启用，CHDIR 会如下改变:
1.当前的目录字符串会被转换成使用磁盘名上的大小写。
2.CHDIR 命令不把空格当作分隔符，因此有可能将目录名改为一个带有空格但不带有引号的子目录名。例如：
cd \winnt\profiles\username\programs\start menu
而在扩展功能停用的情况下，您必须像这样键入命令：
cd "\winnt\profiles\username\programs\start menu"
Displays the name of or changes the current directory.
CHDIR [/D] [drive:][path]
CHDIR [..]
CD [/D] [drive:][path]
CD [..]
.. Specifies that you want to change to the parent directory.
Type CD drive: to display the current directory in the specified drive.
Type CD without parameters to display the current drive and directory.
Use the /D switch to change current drive in addition to changing current directory for a drive.
If Command Extensions are enabled CHDIR changes as follows:
The current directory string is converted to use the same case asthe on disk names. So CD C:\TEMP would actually set the current directory to C:\Temp if that is the case on disk.
CHDIR command does not treat spaces as delimiters, so it is possible to CD into a subdirectory name that contains a space without surrounding the name with quotes. For example:
cd \winnt\profiles\username\programs\start menu
is the same as:
cd "\winnt\profiles\username\programs\start menu"
which is what you would have to type if extensions were disabled.
