// filePattern -----> .xml, .doc,.....
private List getFileLocation(FilePath dir, str filePattern)
{
    FilePath sFilePath;
    FileName fileName;

    List fileList = new List(Types::String);
    System.IO.DirectoryInfo di;
    System.IO.FileInfo[] fis;
    System.IO.FileInfo fi;

    int i;
    int l;
    ;

    sFilePath = dir;
    //BP Deviation Documented
    di = new System.IO.DirectoryInfo(sFilePath); // get file path directory
    fis = di.GetFiles(filePattern);             // filter the  file based on given file pattern
    l = fis.get_Length();

    for (i = 0; i < l; i++)
    {
        fi = fis.GetValue(i);
        fileName = fi.get_FullName();
        fileList.addEnd(fileName);
    }
    return fileList;
