Your syntax is incorrect. You can't use <code>ELSE IF</code>. It appears that you don't really need it anyway. Simply use multiple <code>IF</code> statements:

<pre><code>IF %F%==1 IF %C%==1 (
 ::copying the file c to d
 copy "%sourceFile%" "%destinationFile%"
 )

IF %F%==1 IF %C%==0 (
 ::moving the file c to d
 move "%sourceFile%" "%destinationFile%"
 )

IF %F%==0 IF %C%==1 (
 ::copying a directory c from d, /s: boş olanlar hariç, /e:boş olanlar dahil
 xcopy "%sourceCopyDirectory%" "%destinationCopyDirectory%" /s/e
 )

IF %F%==0 IF %C%==0 (
 ::moving a directory
 xcopy /E "%sourceMoveDirectory%" "%destinationMoveDirectory%"
 rd /s /q "%sourceMoveDirectory%"
 )
</code></pre>

AFAIK you can't do an <code>if else</code> in batch like you can in other languages, it has to be nested <code>if</code>'s.

Using nested <code>if</code>'s your batch would look like

<pre><code>IF %F%==1 IF %C%==1(
 ::copying the file c to d
 copy "%sourceFile%" "%destinationFile%"
 ) ELSE (
 IF %F%==1 IF %C%==0(
 ::moving the file c to d
 move "%sourceFile%" "%destinationFile%"
 ) ELSE (
 IF %F%==0 IF %C%==1(
 ::copying a directory c from d, /s: boş olanlar hariç, /e:boş olanlar dahil
 xcopy "%sourceCopyDirectory%" "%destinationCopyDirectory%" /s/e
 ) ELSE (
 IF %F%==0 IF %C%==0(
 ::moving a directory
 xcopy /E "%sourceMoveDirectory%" "%destinationMoveDirectory%"
 rd /s /q "%sourceMoveDirectory%"
 )
 )
 )
 )
</code></pre>

or as James suggested, chain your <code>if</code>'s, however I think the proper syntax is

<pre><code>IF %F%==1 IF %C%==1(
 ::copying the file c to d
 copy "%sourceFile%" "%destinationFile%"
 )
</code></pre>

I think in the question and in some of the answers there is a bit of confusion about the meaning of this pseudocode in DOS: IF A IF B X ELSE Y. It does not mean IF（A and B) THEN X ELSE Y, but in fact means IF A( IF B THEN X ELSE Y). If the test of A fails, then he whole of the inner if-else will be ignored.

As one of the answers mentioned, in this case only one of the tests can succeed so the 'else' is not needed, but of course that only works in this example, it isn't a general solution for doing if-else.

There are lots of ways around this. Here is a few ideas, all are quite ugly but hey, this is (or at least was) DOS!

<pre><code>@echo off

set one=1

IF %one%_%two%==1_1 (

<code>IF...ELSE IF</code> constructs work very well in batch files, in particular when you use only one conditional expression on each IF line:

<pre><code>IF %F%==1 (
 ::copying the file c to d
 copy "%sourceFile%1" "%destinationFile1%"
) ELSE IF %F%==0 (
 ::moving the file e to f
 move "%sourceFile2%" "%destinationFile2%" )
</code></pre>

In your example you use <code>IF...AND...IF</code> type construct, where 2 conditions must be met simultaneously. In this case you can still use <code>IF...ELSE IF</code> construct, but with extra parentheses to avoid uncertainty for the next ELSE condition:

<pre><code>IF %F%==1 (IF %C%==1 (
 ::copying the file c to d
 copy "%sourceFile1%" "%destinationFile1%" )
) ELSE IF %F%==1 (IF %C%==0 (
 ::moving the file e to f
 move "%sourceFile2%" "%destinationFile2%"))
</code></pre>

The above construct is equivalent to:

<pre><code>IF %F%==1 (
 IF %C%==1 (
 ::copying the file c to d
 copy "%sourceFile1%" "%destinationFile1%"
 ) ELSE IF %C%==0 (
 ::moving the file e to f
 move "%sourceFile2%" "%destinationFile2%"))
</code></pre>

Processing sequence of batch commands depends on <a href="https://stackoverflow.com/questions/4094699/how-does-the-windows-command-interpreter-cmd-exe-parse-scripts">CMD.exe parsing order</a>. Just make sure your construct follows that logical order, and as a rule it will work. If your batch script is processed by Cmd.exe without errors, it means this is the correct (i.e. supported by your OS Cmd.exe version) construct, even if someone said otherwise.
