> I've tried running "mv a b" with success. Doesn't mv use rename()?
No; IIRC, it is basically a cp followed by an rm, code-wise.
Then again, it's been a while since I fiddled with fileutils, so I
may be wrong.

Below is a simple program that lowercases all file and directory
names in the current dir. Does this work on WinME too?
Make sure you try it in a variety of places (network drives, dirs
with LFN files, SUBSTed drives, ...).

== start of simple proglet
#include <stdio.h>
#include <string.h>
#include <dirent.h>
#include <ctype.h>

int __opendir_flags = __OPENDIR_PRESERVE_CASE;

void
decapitate(const char* name)
{
static char lowername[512];
  /* Don't change a CVS directory */
  if (strcasecmp (name, "CVS") == 0)
    return;
  strcpy (lowername, name);
  strlwr (lowername);
  if (strcmp (name, lowername) != 0) {
    printf ("%s -> %s\n", name, lowername);
    if (rename (name, lowername) != 0) {
      perror (name);
    }
  }
}

int
main(void)
{
DIR* dp = NULL;
struct dirent* ep = NULL;
  dp = opendir ("./");
  if (dp != NULL) {
    while ((ep = readdir (dp)) != NULL)
      decapitate (ep->d_name);
    (void) closedir (dp);
  }
  else puts ("Couldn't open the directory.");
  return 0;
}
