Where does Katalon Recorder store the test suites and/or test cases?

I created a test suite with test cases. I closed the suite yesterday and now I want to open it back up and create some new test cases. However, I can’t find my test suite or my test cases.

If you right clicked on it and selected Close then you may have actually lost these. Katalon Recorder offers a Save Suite option that saves it to a file (wherever you choose) and this file can then be re-imported later if you close the suite.

Not sure where it stores the test cases sitting within the tool, but at a guess it has its own custom database file that it keeps it in (that potentially sits inside its own plugin directory).
