Hi my friend,
You should count them. The below code can help you

function DirCount(Dir: string): integer;  // Dir Should be teminated with \
var
  sr: TSearchRec;
  n: integer;
begin
  n:= 0;;
  if FindFirst(Dir+'*.*', faDirectory, sr) = 0 then
  begin
    repeat
      if (sr.Attr and faDirectory)=sr.Attr then
        Inc(n);
    until FindNext(sr) <> 0;
    FindClose(sr);
  end;
  Result:= n;
end;

Hi again,
 .... and if you want to Have its name try this one

function DirCount(Dir: string; var DirList: TStrings): integer;  // Dir Should be teminated with \
var
  sr: TSearchRec;
  n: integer;
begin
  n:= 0;;
  if FindFirst(Dir+'*.*', faDirectory, sr) = 0 then
  begin
    repeat
      if (sr.Attr and faDirectory)=sr.Attr then
      begin
        Inc(n);
        DirList.Add(sr.Name);
     end;
    until FindNext(sr) <> 0;
    FindClose(sr);
  end;
  Result:= n;
end;

... Maybe this code heps you:

function DirCount(Dir, FTPTargetDir: string): integer;  // Dir Should be teminated with \
var
  sr: TSearchRec;
  n: integer;
begin
  n:= 0;;
  if FindFirst(Dir+'*.*', faDirectory, sr) = 0 then
  begin
    repeat
      if (sr.Attr and faDirectory)=sr.Attr then
      begin
        Inc(n);
        idftp1.MakeDir(FTPTargetDir+sr.Name)
      end;
    until FindNext(sr) <> 0;
    FindClose(sr);
  end;
  Result:= n;
end;

Hi,
I am very glad, I try to help you more ...  (if I can)
If You want to create the structure in the main FTP dir, you can pass the ftptargetdir by '' value (it can be used for create the structure in a subdir in main FTP folder)
and if you want to create subfolders you should use recursive function like below code:

function CopyDirStruct(Dir, FTPTargetDir: string): integer;  // Dir & FTPTargetDir Should be teminated with \
var
  sr: TSearchRec;
  n: integer;
begin
  n:= 0;
  if FindFirst(Dir+'*.*', faDirectory, sr) = 0 then
  begin
    repeat
      if ((sr.Attr and faDirectory)=sr.Attr) and (Pos('.', sr.Name)=0) then
     begin
        idftp1.MakeDir(FTPTargetDir+sr.Name);
        n:= n + CopyDirStruct(Dir+sr.Name+'\', FTPTargetDir+sr.Name+'\');
     end;
    until FindNext(sr) <> 0;
    FindClose(sr);
  end;
  Result:= n;
end;

Example of using:
  1- CopyDirStruct('C:\TestDir\', ''); // copy the Dir structure under C:\TestDir to root of FTP Dir
  2- CopyDirStruct('C:\TestDir\', 'MyFolder\'); // copy the Dir structure under C:\TestDir to MayFolder of FTP Dir

Ok,
sorry for delay, if you want to put total structure in primary folder please check this: (attention there is two functions)

function CopySubDirStruct(Dir, FTPTargetDir: string): integer;  // Dir & FTPTargetDir Should be teminated with \
var
  sr: TSearchRec;
  n: integer;
begin
  n:= 0;
  if FindFirst(Dir+'*.*', faDirectory, sr) = 0 then
  begin
    repeat
      if ((sr.Attr and faDirectory)=sr.Attr) and (Pos('.', sr.Name)=0) then
     begin
        idftp1.MakeDir(FTPTargetDir+sr.Name);
        n:= n + CopySubDirStruct(Dir+sr.Name+'\', FTPTargetDir+sr.Name+'\');
     end;
    until FindNext(sr) <> 0;
    FindClose(sr);
  end;
  Result:= n;
end;

function CopyDirStruct(Dir, FTPTargetDir: string): integer;
var
  PrimaryDir: string;
begin
  if (Copy(Dir, Length(Dir), 1)<>'\') then
    Dir:= Dir + '\';
  if (Copy(FTPTargetDir, Length(FTPTargetDir), 1)<>'\') then
    FTPTargetDir:= FTPTargetDir + '\';
  PrimaryDir:= ExtractFileName(ExtractFileDir(Dir));
  idftp1.MakeDir(FTPTargetDir+PrimaryDir);
  Result:= CopySubDirStruct(Dir, FTPTargetDir+PrimaryDir+'\');
end;

Example of using:
  1- CopyDirStruct('C:\TestDir\', ''); // copy the TestDir and below structure  to root of FTP Dir
  2- CopyDirStruct('C:\TestDir\', 'MyFolder\'); // copy the TestDir and below structure to MayFolder of FTP Dir

You can not create directory with ftp in the manner you are trying here
This will not work

For each subdirectory you are creating, you have to change the working directory (CWD) to the immediate parent.
Then simply call MakeDir(SubDirectory)

Example if you have the structure Home/Dir2/Dir3

You first have to change directory to Dir2 -  CWD(Dir2)
Once this is successful, call MakeDir(Dir3)

A simple implementation of FindFirst will not do either

Think objects, create an object that will hold the file names and the directories they belong to.
When transferring the files, start with the files in the Root of your object, then go to each subdirectory one level at a time, this way you call makedir only once for a group of files

Ok, we should note to ewangoya comment, and correct the code like this

function CopyDirStruct(Dir, FTPTargetDir: string): integer;  // Dir & FTPTargetDir Should be teminated with \ and /
var
  sr: TSearchRec;
  n: integer;
begin
  n:= 0;
  if FindFirst(Dir+'*.*', faDirectory, sr) = 0 then
  begin
    repeat
      if ((sr.Attr and faDirectory)=sr.Attr) and (Pos('.', sr.Name)=0) then
     begin
        if (FTPTargetDir='') then
          idftp1.ChangeDir('/')
        else idftp1.ChangeDir(FTPTargetDir);
        idftp1.MakeDir(sr.Name);
        n:= n + CopySubDirStruct(Dir+sr.Name+'\', FTPTargetDir+sr.Name+'/');
     end;
    until FindNext(sr) <> 0;
    FindClose(sr);
  end;
  Result:= n;
end;

unfortunately i cant test this code please test and tell me again.
Best regards
Reza
