New approach for Winapp2.ini in CCleaner Suggestions Posted October 13 · Report reply - I have a suggestion on how to increase to amount of applications that are supported by CCleaner. 1) Dump every definition for every program in one file (E.g. "Winapp2.ini"). I know that this file will grow, grow and grow as time goes by and that this will increase the amount of time CCleaner needs to go through all the definitions in that file. 2) To reduce the amount of time CC needs to search through that list, create a second list (e.g. Winapp3.ini") which contains only a (very) few definitions (when CC is installed) like for e.g. MS Internet Explorer, MS Edge, MS Edge (chromium based), CHrome, Firefox, etc. In other words programs that are (still) used on very frequent basis. 3) Let CC search for the program "footprints" that are contained in that first list ("winapp2.ini"). Do that with a (VERY) low priority and in a separate process. Each time CC finds a match in that file/list, copy that definition/foot print to the second list (E.g. "Winapp3.ini".) That way this 2nd list will only have a very modest size and can be executed in a very limited amount of time. 4) Add somewhere a button or an option called "Update definitions now". This option then forces CC to update that "Winapp3.ini" file without a delay and with high priority.
