How to detect upper/lower case diffs in file/folder names in dir tree? Robocopy feature?

The problem of many so called "synchronization" tools is that they simply backup a
directory tree from one source to a target. Almost all of them do NOT detect changes
in upper/lower case of file or folder names.

So assume I have two absolute equal directory trees beginning with

D:\myprojects\*
and
W:\backup\myprojects\v2009\*

Now I change some chars in a folder name in the source from lower to upper case
resp. vice versa e.g.

D:\myprojects\l1b\versionAA12\*
to
D:\myprojects\lib\Versionaa12\*

This change is NOT detected by standard sync/backup programs. The folder name in the target dir
remains untouched.

Is there a tool which allows the detection of upper/lower case changes/differences?

Does e.g. Robocopy detect them (with a special option) ?

While the "ren" (rename) command will rename files according to the
capitalisation you type, all of the "copy" commands I know will retain the
upper/lower case of the target file, regardless of the way the source file
name is spelt. You would have to write a batch or VB Script file to
synchronise file name capitalisation.

Is this portion of the source path...\l1b\

supposed to be the same as this one? \lib\

If so, do you want to have just both AA12 and aa12 in the destination? If
so, you can't because DOS considers them to be the same and you can't have
two directories with the same name in a directory.

Or do you want the AA12 directory in the destination to be changed to aa12?
If so, what basis would you think a program could use to effect that change?
Folders have a creation date but none for modified so you can't use that;
even if they had a "modified date", DOS wouldn't consider swapping case as a
modification because even if the long file name changed, the DOS directory
entry wouldn't.

As others said, you could write something to do it but frankly I think you'd
be money ahead to find a way of differentiating other than case...maybe AA12
to AA-12 or -AA12. Dates are always good too, 20090728_AA12, eg.
