I am on Win7 and I got into troublex when I tried to remove the page group information from the pdf files. All the pdfs are empty now.

Now I would like to convert all the svgs in that directory to pdf and use the

gs -o image.pdf -sDEVICE=pdfwrite -dColorConversionStrategy=/CMYK -dProcessColorModel=/DeviceCMYK image.pdf as was proposed by this thread on Tex.stackexchange:

http://tex.stackexchange.com/questions/76273/multiple-pdfs-with-page-group-i...

I hope somebody can propose how to use which batch file in windows to perform this task. Sometimes ago I have done this on linux, but it was more than 15 years ago.

thanks for any help

Bernhard
