    You can create a DLL with the code in that previous article and then add it to Dynamics NAV. Then call the DLL and pass the folder path. This will sort your problem.

    You need to go through each file and then delete it or else you need to use .net variable to do it for you.

    Check this one : www.csharp-examples.net/delete-all-files

    You have to do something like this where RecFile is of type Record 2000000022

                     recFile.RESET;

                     recFile.SETRANGE(Path,FolderPath);

                     recFile.SETRANGE("Is a file",TRUE);

                     IF recFile.FINDSET THEN

                       REPEAT

                             FILE.ERASE(FolderPath + recFile.Name);

                       UNTIL recFile.NEXT = 0;

    Hi ramesh,

    Maybe next code will help you ;

    Variables

    DNObj DotNet System.Object.'mscorlib

    DNFolder DotNet System.IO.Directory.'mscorlib

    DNLst DotNet System.Collections.Generic.List`1.'mscorlib

    DNFile DotNet System.IO.File.'mscorlib

    DNPath DotNet System.IO.Path.'mscorlib

    i Integer

    Code

    DNObj := DNFolder.GetFiles('Source folder','*.yourextension');

    DNLst := DNLst.List;

    DNLst.AddRange(DNObj);

    FOR i := 0 TO DNLst.Count - 1 DO BEGIN

     //IN THIS CASE I MOVE THE FILES BUT YOU CAN DELETE

     DNFile.Move(DNLst.Item(i),'Destination      folder'+'\'+DNPath.GetFileName(DNLst.Item(i)));

    END;

    Best Regards,

    Carlos.

    load file list using .net (Directory.GetFiles), iterate through list, delete each file in loop.
