search the forum please.
i don’t remember all of them, but you have to delete the folders like ‘build, lib’ and some .dotfiles.
start a new empty project, note the folder structure in file explorer.
make a simple testcase (it can be empty), run it > inspect the project folder again. you will notice some new folders and dotfiles are created.
those are the runtime files
on the other side, if i remember it right, katalon have somewere a ‘clean up’ option in the menu.
last time i tried was in the 5.x epoch … not working as expected, so i simply forgot it.
but since we are now in the 6.x epoch and 7.x is knocking at the door … chances are this feature has been improved. feel free to search for it
