My website has 100K+ URL ([ External links are visible to forum administrators only ]) so When I create a sitemap using Pro Sitemap generator it's take longtime and after some time it's stopped so I can't make sitemap.

How Can I Splitting the sitemap into multiple files using Unlimited Sitemap generator? or any other option please let me know.

it looks like your server configuration doesn't allow to run the script long enough to create full sitemap. Please try to increase memory_limit and max_execution_time settings in php configuration at your host (php.ini file) or contact hosting support regarding this.
Generator will split sitemap on multiple files automatically.
