MS-DOS Commands :: cd (change directory)
When you are using a Microsoft MS-DOS command window,
MS-DOSworks on one directory at a time. The "current" directory is indicated as part of the command prompt.
For example, the command prompt "C:\mystuff\ebooks>" means that the current directory is the "ebooks" directory which is located inside the "mystuff" directory on the c: drive.
Use the cd command to make a different directory the "current" directory ("cd" is short for "change directory").
The command can be typed as either:
"cd \mystuff"will make "\mystuff" the current directory. To get to the "root" (top level directory) of your c: drive, type cd \
If directory contains spaces, then enclose it with quotation marks. For example:
cd "C:\Documents and Settings\CCC\My Documents\My Music"or cd "My Music"
Make the specified directory directory (or drive:directory) the current directory.
The directory can start with a \ or be relative to the current directory. For example, if the current directory is C:\mystuff then typing
cd ebookswill change the current directory to C:\mystuff\ebooks (assuming that there is in fact a ebooks sub-directoryinside C:\mystuff).
Note: Each drive (c:, d:, e:, etc.) has its own current directory. That's why there is the drive:directory variation of the cd command. For example:
cd e:\photoswill set the current directory of the e: drive to \photos. To switch to the e: drive, you would simply type e: and press the Enter key.
cd /d drive:directory
Make the specified directory directory the current directory and also switch do the drive: drive.
You can also type cd .. (the two dots are required) to back out one level out of the current directory. For example, if the current directory is C:\mystuff\ebooks then typing
cd ..will change the current directory to C:\mystuff
If you type cd without specifying a directory, the cd command will display the directory path of the current directory. Typically you will not use this variation of the cd command since the directory path is shown in the command prompt. It is more useful in batch files.
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 as the 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.
