Excuse me,
Does anyone knows how patch 113646 can be improved?

Thank you very much

Not a real review, I have no clue about shell32. This is just what I
noticed at a quick and pretty uninformed look.

@@ -1426,7 +1426,14 @@ static DWORD move_files(LPSHFILEOPSTRUCTW
lpFileOp, const FILE_LIST *flFrom, con
     }

     if (!PathFileExistsW(flTo->feFiles[0].szDirectory))
-        return ERROR_CANCELLED;
+    {
+        ret = SHCreateDirectoryExW(NULL, flTo->feFiles[0].szDirectory, NULL);
+        if(ret)
+        {
+            ERR("SHCreateDirectoryW failed: %08x\n", ret);
+            return ret;
+        }
+    }

SHCreateDirectoryExW can probably legitimately fail so I don't think
an ERR is appropriate here. A WARN might be okay. While at it, please
add a space between 'if' and '('.

Unrelated preexisting issue, those helper functions for
SHFileOperationW() like move_files() return a DWORD but the error code
is otherwise int. It shouldn't matter in practice but it would be nice
to fix that (in a separate patch).

Hi Matteo,
Thanks for commenting on my patch

I think it could be more challenging than I expected to handle the
errors. I'll look into it deeper.

I agree with you. DWORD is unsigned, but SHFileOperationW returns a
int value. I'll write a patch to fix it,

PS. Thanks to Sebastian Lackner's comment on my patch:
