DEPUPE Crashes and Takes Out The Current TCC Session With It

If I run:

DEDUPE /S /V /H *.* A:\

DEPUPE crashes and takes out the copy of TCC that it is running on. My guess is that running "/S", on the root of a drive "A:\" and "*.*" (basically everything on the drive) will generate a very large dataset. This dataset is probably to large for DEPUPE to handle and cause a buffer overflow.

Also noticed that there is a "/T" switch on the command line description on "DEDUPE /?". Any idea what the switch does?

Thanks
