Re: compare two folders and copy folder/file if not found on target else log that file or folder

in reply to compare two folders and copy folder/file if not found on target else log that file or folder

"...if that folder/file is not found then copy that ..."

Uh, copying an undef or nul seems fairly pointless. Do you mean 'copy what was found in one into the other?'; 'create a log entry documenting what was NOT found in one that was in the other?' or something else?

    Basically i am comparing two folder (source folder and target folder).

    In the target folder the source folder files/subfolders are not found then copy them. Else if it is found then don't copy that file instead log them stating that respective file already exists.

      OK, that's what I suspected and others discerned to be your meaning. Now let me give you a 'simple english' version that's wordy but utterly unambiguous:
      "I'm comparing two folders. If a file or subfolder is NOT found in the second but is present in the first, copy the missing item from the first to the second; otherwise... simply log that a file or dir was found in BOTH folders."

      Note that this expression does NOT concern itself with items found in the second folder, but not the first. That's a different requirement and requires a different problem statement.

      As with programming, communicating anything even mildly complex depends heavily on clarity and precision.
