We have to be much more specific here. If you are using 6.x, the extensions are there, but the file names are not visible at all. You have to read the index.dat files to findout how to translate the numbers into names.
If you are on XI, you're dead in the water. There is no good way that I know of to find the reports as they are pretty much scrambled.
