What is the current directory in a batch file?

I want to create a few batch files to automate a program.

My question is when I create the batch file, what is the current directory? Is it the directory where the file is located or is it the same directory that appears in the command prompt, or something else?

From within your batch file:

%cd% refers to the current working directory (variable)

%~dp0 refers to the full path to the batch file's directory (static)

%~dpnx0 and %~f0 both refer to the full path to the batch directory and file name (static).

See also: What does %~dp0 mean, and how does it work?


Actually, it looks like %~dp0 gives the full path to the directory that the executing batch file is in. %~dpnx0 (which is equivalent to %~f0) gives the full path to the batch file. See robvanderwoude.com/parameters.php for more details.
See also good detailed answers of a similar question: Get list of passed arguments in Windows batch script (.bat)
Unfortunately when run as a process from .net %~dp0 is the working directory not the batch files directory, Found this out the hard way.
As a more explicit example, when right-clicking on a .cmd file and running as administrator, %cd% gives C:\WINDOWS\system32 and %~dp0 gives the batch file directory with trailing slash.
@TwistedCode %~dp0 is referencing drive and path of argument 0 of the batch file arguments. It is NOT an environment variable reference. It is a batch file argument reference. %~dp0 expands to full path of currently processed batch file. A batch file C:\Temp\Devlopement & Test()!\Main.bat with %~dp0 expanding to C:\Temp\Devlopement & Test()!\ on execution can call the batch file C:\Temp\SubBatch.cmd, for example with call "%~dp0..\SubBatch.cmd", containing also %~dp0 expanding on execution to C:\Temp\. Run call /? in a cmd window for help.

It usually is the directory from which the batch file is started, but if you start the batch file from a shortcut, a different starting directory could be given. Also, when you'r in cmd, and your current directory is c:\dir3, you can still start the batch file using c:\dir1\dir2\batch.bat in which case, the current directory will be c:\dir3.

In a batch file, %cd% is the most commonly used command for the current directory, although you can set your own variable:

set mypath=%cd%
echo %mypath% (where %mypath% is the current directory that the batch file is sitting in)

So say you were wanting to open Myprog.exe. If it was in the same folder, you would use the command:

start %mypath%\Myprog.exe

That would open Myprog from the current folder.

The other option is to make a directory in C: called AutomatePrograms. Then, you transfer your files to that folder then you can open them using the following command:

start "" "C:\AutomatePrograms\Myprog1.exe"
start "" "C:\AutomatePrograms\Myprog2.exe"
start "" "C:\AutomatePrograms\Myprog3.exe"

As noted in the top answer here, %cd% is variable, so running the batch file from Windows Explorer as admin will give C:\WINDOWS\system32 which is almost certainly not what you want. %~dp0 is more consistent.

Say you were opening a file in your current directory. The command would be:

 start %cd%\filename.filetype

I hope I answered your question.

It is the directory from where you run the command to execute your batch file.

As mentioned in the above answers you can add the below command to your script to verify:

> set current_dir=%cd%
> echo %current_dir%

It is the directory from where you start the batch file. E.g. if your batch is in c:\dir1\dir2 and you do cd c:\dir3, then run the batch, the current directory will be c:\dir3.

%__CD__% , %CD% , %=C:%

There's also another dynamic variable %__CD__% which points to the current directory but unlike %CD% it has a backslash at the end. This can be useful if you want to append files to the current directory. Also %CD% does not work under disabled extensions environment ,but %__CD__% always works.

With %=C:% %=D:% you can access the last accessed directory for the corresponding drive. If the variable is not defined you haven't accessed the drive on the current cmd session.

And %__APPDIR__% expands to the executable that runs the current script a.k.a. cmd.exe directory.

Just my 2 cents. The following command fails if called from batch file (Windows 7) placed on a pendrive:

%SystemRoot%\System32\xcopy.exe /e /i "%cd%Ala" "C:\KS\Ala\"

But this does the job:

%SystemRoot%\System32\xcopy.exe /e /i "%~dp0Ala" "C:\KS\Ala\"

This is the switch that I was looking for to determine the parent directory path of my bat file without that batch file name: %~dp0

Your bat file should be in the directory that the bat file is/was in when you opened it. However if you want to put it into a different directory you can do so with cd [whatever directory]
