Visual D dustmite

[Alex]

Suspicious file found: D:\.dustmite\build.dustmite.bat
You should use a clean copy of the source tree.
If it was your intention to include this file in the file-set to 
be reduced,
re-run dustmite with the --force option.

adding force, it then asks me to overwrite dir, then I get

D:\.dustmite\Repos\S\S: The process cannot access the file 
because it is being used by another process.

dustmite --strip-comments --no-redirect --split *.bat:lines 
D:\.dustmite "build.dustmite.bat 2>&1 | find \"Internal error\""

Ultimatly dustmite does nothing.
