Renaming directories in DOS.

Bonjour,
I would like to rename a whole series of directories by changing the extension.
I created a batch for that.
My problem is that with this batch I can add an extension but not replace the existing one.

Here is my script:
this one adds the extension I want:

rem for /F %%i in ('dir/B') DO RENAME %%i %%i.txt

but to remove the extension that existed before, I tried the following script but it does not work:

FOR /F %%i in ('dir/B') DO (ECHO %%i) | FOR /F "tokens=1 delims=." %%j in ('findstr "<.doc"') DO RENAME %%i %%j.txt

Moreover, I was inspired by scripts found on the net but I do not see what "tokens" and "delims" are for...

Could we get some help? 
Configuration: Windows 2000 Internet Explorer 6.0

    Hello,
    is it to change .doc to .txt?

    It seems to me that: 
    rename .doc .txt *.doc
    should work (well it works under linux...)

    Ah, I'll need to change my OS then. It doesn't work under DOS.

      I tested under DOS: 
      rename *.doc *.txt

      it seems to work, but it only works for files present in the directory where you are.
      It's up to you to add the loop to traverse the directories

    Indeed, it works well like this with the files.
    But it's not exactly what I want to do; actually, it's directories that I would like to rename, but it's my fault, I should have specified.

      Are the names of your folders in a specific format?
      I must admit that I don't quite see what you're trying to do...

    Yes, these are folders that need to be automatically retrieved by an FTP. However, they are only processed by the batch script if they have a specific extension. I used .doc or .txt just as an example, but actually, they have other extensions specific to our software packages.

    What’s strange is that the following script works. But I don't see how to remove the initial extension.
    It’s easy with files, but with folders, the command line doesn’t seem to recognize the ""*.*"".
    for /F %%i in ('dir/B') DO RENAME %%i %%i.dem

    Thanks anyway for your help.

    For directories or files, the exact syntax is:

    c:\test> for /F %i in ('dir/B') DO RENAME %i %i.txt

    you must be in the directory containing the files and directories to rename.
    you can change the txt extension to something else, for example Gadget.

    MOVE

    Move files and rename files and directories.

    To move one or more files:
    MOVE | /-Y [drive:][path]file1[,...] destination

    To rename a directory:
    MOVE | /-Y [drive:][path]dir1 dir2
    [drive:][path]file1 Specifies the location and name of the file(s) you want to move.
    destination Specifies the new location of the file.
    Destination can be a drive letter followed by
    a colon (:), a directory name, or a combination. If you are moving a single file,
    you can also include a filename if you want to rename the file while moving it.
    [drive:][path]dir1 Specifies the directory you want to rename.
    dir2 Specifies the new name of the directory.

    /Y Suppresses confirmation prompt for
    replacing existing destination files.
    /-Y Causes confirmation prompt for
    replacing existing destination files.

    The /Y option may be present in the COPYCMD environment variable.
    Override this by using /-Y in the command line. By default, a
    confirmation prompt appears unless the MOVE command is executed from
    a command script.
