A less space expensive way is to
zip all files in the Conquests root dir plus the text folder into a zip file called conquests1_15.zip
run the patch
zip all files in the Conquests root dir plus the text folder into a zip file called conquests1_22.zip
when ever you want to run either one....just right click on the zip file and select "extract here"
and select yes to overwrite existing files.
Thats it....only drawback is that is not shortcutable.
