In batch files, as in standard C programs, argument 0 contains the path to the currently executing script. You can use <code>%~dp0</code> to get only the path portion of the 0th argument (which is the current script) - this path is always a fully qualified path.

You can also get the fully qualified path of your first argument by using <code>%~f1</code>, but this gives a path according to the current working directory, which is obviously not what you want. 

Personally, I often use the <code>%~dp0%~1</code> idiom in my batch file, which interpret the first argument relative to the path of the executing batch. It does have a shortcoming though: it miserably fails if the first argument is fully-qualified.

If you need to support both relative and absolute paths, you can make use of <a href="https://stackoverflow.com/questions/1645843/batch-file-resolve-absolute-path-from-relative-path-and-or-file-name/4488734#4488734">Frédéric Ménez's solution</a>: temporarily change the current working directory. 

Here's an example that'll demonstrate each of these techniques:

<pre><code>@echo off
echo %%~dp0 is "%~dp0"
echo %%0 is "%0"
echo %%~dpnx0 is "%~dpnx0"
echo %%~f1 is "%~f1"
echo %%~dp0%%~1 is "%~dp0%~1"

rem Temporarily change the current working directory, to retrieve a full path 
rem to the first parameter
pushd .
cd %~dp0
echo batch-relative %%~f1 is "%~f1"
popd
</code></pre>

If you save this as c:\temp\example.bat and the run it from c:\Users\Public as

c:\Users\Public>\temp\example.bat ..\windows

...you'll observe the following output:

<pre><code>%~dp0 is "C:\temp\"
%0 is "\temp\example.bat"
%~dpnx0 is "C:\temp\example.bat"
%~f1 is "C:\Users\windows"
%~dp0%~1 is "C:\temp\..\windows"
batch-relative %~f1 is "C:\Windows"
</code></pre>

This is to help fill in the gaps in Adrien Plisson's answer (which should be upvoted as soon as he edits it ;-):
<blockquote>

unfortunately, i don't know how to mix the 2 together...
</blockquote>
One can handle <code>%0</code> and <code>%1</code> likewise:
<ul>
<li><code>%~dpnx0</code> for fully qualified drive+path+name+extension of the batchfile itself, 
<code>%~f0</code> also suffices;</li>
<li><code>%~dpnx1</code> for fully qualified drive+path+name+extension of its first argument [if that's a filename at all], 
<code>%~f1</code> also suffices;</li>
</ul>
<code>%~f1</code> will work independent of how you did specify your first argument: with relative paths or with absolute paths (if you don't specify the file's extension when naming <code>%1</code>, it will not be added, even if you use <code>%~dpnx1</code> -- however.
But how on earth would you name a file on a different drive anyway if you wouldn't give that full path info on the commandline in the first place?
However, <code>%~p0</code>, <code>%~n0</code>, <code>%~nx0</code> and <code>%~x0</code> may come in handy, should you be interested in path (without driveletter), filename (without extension), full filename with extension or filename's extension only. But note, while <code>%~p1</code> and <code>%~n1</code> will work to find out the path or name of the first argument, <code>%~nx1</code> and <code>%~x1</code> will not add+show the extension, unless you used it on the commandline already.

The following did the trick:

set REL_PATH=..\..\
set ABS_PATH=

rem // Save current directory and change to target directory
pushd %REL_PATH%

rem // Save value of CD variable (current directory)
set ABS_PATH=%CD%

echo Relative path: %REL_PATH%
echo Maps to path: %ABS_PATH%

I have not seen many solutions to this problem. Some solutions make use of directory traversal using CD and others make use of batch functions. My personal preference has been for batch functions and in particular, the <a href="http://www.dostips.com/DtCodeCmdLib.php#Function.MakeAbsolute" rel="nofollow noreferrer">MakeAbsolute</a> function as provided by DosTips.
The function has some real benefits, primarily that it does not change your current working directory and secondly that the paths being evaluated don't even have to exist. You can find some helpful tips on how to use the function <a href="http://blogs.dayneo.co.za/2012/02/evaluate-relative-paths-using-dos.html" rel="nofollow noreferrer">here</a> too.
Here is an example script and its outputs:

Without having to have another batch file to pass arguments to (and use the argument operators), you can use <code>FOR /F</code>:

<pre><code>FOR /F %%i IN ("..\relativePath") DO echo absolute path: %%~fi
</code></pre>

where the <code>i</code> in <code>%%~fi</code> is the variable defined at <code>/F %%i</code>. eg. if you changed that to <code>/F %%a</code> then the last part would be <code>%%~fa</code>.

To do the same thing right at the command prompt (and not in a batch file) replace <code>%%</code> with <code>%</code>...

it looks odd with \..\ in the middle of your path but it works. No need to do anything crazy :)

blocks|key|3081708|text|现在PowerShell非常常见，所以我经常使用它作为调用C#的一种快捷方式，因为它有几乎所有的函数：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3081709|@echo+off

PowerShell is pretty common these days so I use it often as a quick way to invoke C# since that has functions for pretty much everything:

<pre><code>@echo off
set pathToResolve=%~dp0\..\SomeFile.txt
for /f "delims=" %%a in ('powershell -Command "[System.IO.Path]::GetFullPath( '%projectDirMc%' )"') do @set resolvedPath=%%a

echo Resolved path: %resolvedPath%
</code></pre>

It's a bit slow, but the functionality gained is hard to beat unless without resorting to an actual scripting language.

With <code>..</code> being your relative path, and assuming you are currently in <code>D:\Projects\EditorProject</code>:

<code>cd .. &amp; cd &amp; cd EditorProject</code> (the relative path)

Is there a way in a Windows batch script to return an absolute path from a value containing a filename and/or relative path?

Given:

<pre><code>"..\"
"..\somefile.txt"
</code></pre>

I need the absolute path relative to the batch file.

Example:

<ul>
<li>"somefile.txt" is located in "C:\Foo\"</li>
<li>"test.bat" is located in "C:\Foo\Bar". </li>
<li>User opens a command window in "C:\Foo" and calls <code>Bar\test.bat ..\somefile.txt</code></li>
<li>In the batch file "C:\Foo\somefile.txt" would be derived from <code>%1</code></li>
</ul>
