matlab，movefile未知错误

Question

错误发生在最后一步，Matlab说它出现了未知错误＆＃34;。

以下是我的代码。它是实现这一点：解压zip.file，读取所有解压缩的文件并在每个文件中搜索某些特定信息（Information1_ID，Information2_ID，Information3_ID，Information4_ID）。将Information4_ID与许多文件夹的名称进行比较。如果其中两个相同，请将文件移动到相应的文件夹中。

你们可以告诉我可能导致这个错误的原因吗？

% unzip the file    into the folder named 'zp'

     unzip('ResultLogs_10_20121012_76708.52.zip','E:\matlab\zp');

%  the path of the files after unzipped

     Fileinzip = dir('E:\matlab\zp\m2000\AmpDetect.server\logs'); 

     cd('E:\matlab\zp\m2000\AmpDetect.server\logs');

     Length = length(Fileinzip);

   % this loop go though the unzipped files

    for i = 3:Length   
    FilesName = Fileinzip(i).name;
  %  read the file and get some certain information

     delimiter = '\t';
     starRow = 1;
     endRow = inf;
     formatSpec = '%s %s %*[^\n]';

     fileID = fopen(FilesName);

    resultArray = textscan(fileID,formatSpec,endRow+1,'Delimiter',delimiter,'EmptyValue',-Inf,'HeaderLines',starRow-1,'ReturnOnError',false);

     FAM1 = 'Plate Name';
     FAM1_ID = strmatch(FAM1,resultArray{1,1}); 

     FAM2 = 'Time Stamp AD Start';
     FAM2_ID = strmatch(FAM2,resultArray{1,1});

     FAM3 = 'AD Serial Num';
     FAM3_ID = strmatch(FAM3,resultArray{1,1});

     FAM4 = 'AD App Id';
     FAM4_ID = strmatch(FAM4,resultArray{1,1});

     Information = resultArray{1,2};
     Information1_ID = Information(FAM1_ID);
     Information2_ID = Information(FAM2_ID);
     Information3_ID = Information(FAM3_ID);
     Information4_ID = Information(FAM4_ID);

     Folder_database = dir('E:\matlab\Database\Close Mode');

     Length_folder = length(Folder_database);

% go through the folders name

     for rr = 3:Length_folder 
     Folder_Name = Folder_database(rr).name; 
% if same, rename the file and move the file into the corresponding folder

     if strcmp(Information4_ID,Folder_Name) 


            path = 'E:\matlab\zp\m2000\AmpDetect.server\logs'
            oldpath = 'E:\matlab\zp\m2000\AmpDetect.server\logs';
            newpath = strcat('E:\matlab\zp\m2000\AmpDetect.server\logs','\', Folder_Name); % moved to a new path 

            Folder_Name = strcat(Information4_ID,'_',Information3_ID,'_',Information2_ID,'_',Information1_ID);

            movefile(oldpath,newpath); 
     end
  end
