Command prompt won't change directory to another drive

As @nasreddine answered or you can use /d

cd /d d:\Docs\Java

For more help on the cd command use:

C:\Documents and Settings\kenny>help cd

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.

The directory you're switching to is on another drive, you need to switch to that drive using :

C:\...\Admin> d:

then you can cd into the directory you want.

C:\...\Admin> d:
D:\>cd "Docs\Java"

D:\Docs\Java>

Use drive letter d for changing to D drive like:

  C:\> d:

When changing drives, you just need to type the drive letter, like d: (don't use the backslash, like d:\; it doesn't work).

You only use cd when moving between directories within the same drive.
