using DIVA-GIS to convert environmental data

i have been working with arcgis unsuccessfully, so i decided to try out diva-gis. i don't know much about it, meaning it's functions.

i ask: can i convert generic grid data, downloaded from worldclim, to esri ascii grid... because the main software i have to use is MAXENT which needs *.asc files

i'll be waiting for answers, thank you
