That is of little consequence, the bulk of the conversion is with the *content* of the @file. If you have a too looong command line, and all the files on it needs to be converted since they are moved into the @file, doing the extra conversion on the @file itself should drown in the noise. The performance gain in this case would be to realize that since we are on MSYS, we should avoid taking the @file branch like the plague, and rely on the much faster command line conversion until we desperately must use an alternative. >> since the manual forking conversion is so much slower than the >> automatic command line conversion.

See above, I don't think that single conversion matters much. Cheers, Peter
