The TOPC file extension is associated with TopicCrunch, a Windows search engine optimization tool. A TOPC file contains search project data in ASCII format, including keywords, domains and search engine settings.
TopicCrunch uses these files to save search projects and allow the configured SEO checks to be run again without entering the settings from scratch.
Open a .topc file with TopicCrunch on Microsoft Windows. Use the program's Open command and select the file; a general text editor may display its ASCII contents but will not load the project as a TopicCrunch search project.
Use TopicCrunch to work with a .topc file and its saved project settings. No conversion is needed to rerun the saved search project.
