I'm also curious why there are no .frm files here. I tried doing a completely fresh 5.5 install on my other Windows 2003 server and made some dummy INNODB tables. They do have matching .frm files. But on this old server's hard drive, there are only the three main INNODB files and none of those .frm files. I do see the .frm files in the old 5.1 directory, but I don't see any in the 5.5 after my upgrade. Could it still have been pointing to those old 5.1 .frm files somehow, while using the three main large files that were in the 5.5 directory?
