This is maybe more a Windows (11) question than it is a dustmite 
one. Semi-OT.

I'm trying to reduce 
https://forum.dlang.org/thread/muehtdyjabmjxosmjuvf forum.dlang.org, and it's
Windows so I don't know what I'm doing. After multiple attempts at piecing
together a batch tester script that both checks for compiler stderr/stdout
*and* the errorlevel of the process, I resigned and wrote a quick thing in D to
do it instead.

Off the top of my head;

```d
import std;

static immutable command = `ldc2.exe -flags and stuff copy/pasted 
from dub build -v output`
     .replace('\\', '/')
     .split(' ');

int main()
{
     immutable result = execute(command);
     return ((result.code == 5) && !result.output.length) ? 0 : 1;
}
```

Once compiled it seems to work when called manually, and dustmite 
accepts it as a tester, but there are a lot of errors output to 
the console during actual reduction.

 Error while attempting to delete init.lookahead.3203: 
 init.lookahead.3203\source\somefile.d: The process cannot 
 access the file because it is being used by another process.
 Error while attempting to rename init.reduced.inprogress to 
 init.reduced: Attempting to rename file init.reduced.inprogress 
 to init.reduced: Access is denied.

They occur *constantly*, and dustmite halts and waits a full 
second each time before retrying, sometimes with the same message 
repeated some 5 times. (Meaning access to the file was blocked 
for the same 5 seconds.)

Indexing is off for the parent directory. What else can I do?

Disable anti-virus.

If that doesn't help, you could try using Sysinternals Process 
Monitor to check what is accessing the file.
