Is there a program for checking two similar directories for file differences?

Question

Is there a program for comparing one folder and all subfolders with another folder and all subfolders for differences in the files contained in it (presence, absence of files, size and list of file names)?

Usage example: I have 100 DLL files from environment 1, and I want to check whether they differ from them (in size and date) from 100 DLL files in environment 2. Therefore, I copy and paste all the DLL files in environment 1 into the directory A and all DLLs in environment 2 to directory B.

Then I run my program for comparing directories in directories A and B and find out that aha, here is a list of 7 DLLs that have different changed dates and times between the two directories.

EDIT: OS - Windows XP

I like WinMerge , although I don’t know how well it will work with binary files such as DLLs.
