SSIS (File System Task) - Unable to move file [duplicate] - sql

Question

I've created a connection using Microsoft Office 12.0 Access Database Engine OLE DB Provider as Excel Schema to loop through all the sheets in the Excel file as demonstrated in this question How to loop through Excel files and load them into a database using SSIS package?
And using Foreach ADO.NET Schema Rowset Enumerator to loop through the excel files.
Everything is working fine now, but after importing the data from Excel, I wanted to move that file to Archive folder. And tried using a File System Task, but I get the error as
[File System Task] Error: An error occurred with the following error message: "The process cannot access the file because it is being used by another process.".
And I also tried with script task from this link. But I was getting some error and couldn't solve the error as I've got zero knowledge on C#.
Below is the error I've got when I tried to move the files using a script task.
at System.RuntimeMethodHandle.InvokeMethod(Object target, Object[] arguments, Signature sig, Boolean constructor)
at System.Reflection.RuntimeMethodInfo.UnsafeInvokeInternal(Object obj, Object[] parameters, Object[] arguments)
at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)

at Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTATaskScriptingEngine.ExecuteScript().
Update:
Here's my complete code with which I'm trying to move the files.
If I add a breakpoint at enum ScriptResults, I don't get that popup and the task gets completed successfully and the file is also been moved to archive, but if I don't add any breakpoint in the C# code, I get that pop and the file is not moved to archive.

As far as I understand, I think you have a task for looping through sheets and another for looping through files. So you probably have 2 tasks inside a foreach loop. Try making a copy of the file inside the foreach loop with a system task
for the executable
c:\windows\system32\cmd.exe
and for the arguments soemthing like
C COPY "C:\xxx\abc\\Destination_template.accdb" "C:\xxx\abc\\Destination_template.accdb"Destination_template - Kopie.accdb"
Then create a file system task which moves that copy to your archive.
This should do the trick (Maybe not the best approach but should work)
