    <p>I need to <strong>copy a directory form one source form multiple destination</strong>. For example, i copied a file from my <strong>C:</strong> drive and paste it into <strong>many external drives like E:,F:,G:...etc</strong>. For this process i used the following code, </p> <pre><code>set src=%~1 :Loop shift set dest=%~1 if "%dest%"=="" goto :EOF xcopy "%src%" "%dest%" /E goto Loop </code></pre> <p>i saved this code snippet as <strong>.bat in system32 folder</strong>. Then i use this command as </p> <pre><code>C:\Windows\System32&gt;mcopy C:\Users\FSSD\Desktop\Screenshot E: F: </code></pre> <p>i executed this command in my command prompt it executed successfully.</p> <p>Then i tried to implement this command in my java application.</p> <p>My java code is,</p> <pre><code>import java.io.BufferedReader; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; public class MultipleCopy{ public static void main(String args[]) { String exe_Cmd = "c:/Windows/System32/mcopy C:/Users/FSSD/Desktop/Screenshot E: F:"; Runtime r = Runtime.getRuntime(); ProcessBuilder p = new ProcessBuilder(new String[] { "cmd.exe", "/C", exe_Cmd }); Process pro; try { pro = p.start(); InputStream is = pro.getInputStream(); InputStreamReader isr = new InputStreamReader(is); BufferedReader br = new BufferedReader(isr); String line; while ((line = br.readLine()) != null) { System.out.println(line); } } catch (IOException e) { // TODO Auto-generated catch block System.err.println("IO Exception" + e.getMessage()); } } } </code></pre> <p>it was executed without any errors but the files won't copied.</p> <p>My eclipse IDE's console's output is:</p> <pre><code>C:\Users\FSSD\IndigoWorkSpace\Multi_Copy&gt;set src=C:/Users/FSSD/Desktop/Screenshot C:\Users\FSSD\IndigoWorkSpace\Multi_Copy&gt;shift C:\Users\FSSD\IndigoWorkSpace\Multi_Copy&gt;set dest=E: C:\Users\FSSD\IndigoWorkSpace\Multi_Copy&gt;if "E:" == "" goto :EOF C:\Users\FSSD\IndigoWorkSpace\Multi_Copy&gt;xcopy "C:/Users/FSSD/Desktop/Screenshot" "E:" /E C:\Users\FSSD\IndigoWorkSpace\Multi_Copy&gt;goto Loop C:\Users\FSSD\IndigoWorkSpace\Multi_Copy&gt;shift C:\Users\FSSD\IndigoWorkSpace\Multi_Copy&gt;set dest=F: C:\Users\FSSD\IndigoWorkSpace\Multi_Copy&gt;if "F:" == "" goto :EOF C:\Users\FSSD\IndigoWorkSpace\Multi_Copy&gt;xcopy "C:/Users/FSSD/Desktop/Screenshot" "F:" /E C:\Users\FSSD\IndigoWorkSpace\Multi_Copy&gt;goto Loop C:\Users\FSSD\IndigoWorkSpace\Multi_Copy&gt;shift C:\Users\FSSD\IndigoWorkSpace\Multi_Copy&gt;set dest= C:\Users\FSSD\IndigoWorkSpace\Multi_Copy&gt;if "" == "" goto :EOF </code></pre> <p>In this, what is my mistake, how can i get the exact output. Reply me as soon as possible. Thanks in advance...!</p>

    1. COWould it not be easier to use Java to copy the files, instead of having to hassle around with command line? The new java.nio Classes introduced with Java 7 would make you use case trivial to implement using `Files.copy()`. Also your solution would be portable as opposed to only working on your PC.

    3. COSure, why not. First you copy the file to the first destination, then to the second destination, and so on, just like you do in your batch file.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
