Output classification predictions to CSV in Weka--where is output file saved?

Question

Answers to this question explain how to output classification predictions to CSV in Weka in both Weka 3.6 (right / option-click model and then save predictions) and 3.7 (choose more options and select Output predictions).

In Weka 3.7, I chose more options, selected Output predictions, and chose CSV as the specific type of output. An answer suggests to "Click on 'outputFile' and select a folder and type a filename." However, I cannot see 'outputFile' or where the CSV output is saved.

Where is the output file saved, or how can I click on 'outputFile' to name the output?

Answer 1

In Weka 3.7.12 on OSX, I was able to find 'outputFile' and the other options by clicking on the whitebox containing CSV (after choosing CSV first), much like how you specify the options for certain classifiers by clicking on those whiteboxes. For me I wasn't able to type a filename, but if I created a blank file manually, I was able to correctly save the output the predictions to that file.

Answer 2

If I left click on CSV (once I've selected it first), WEKA allows me to select an existing CSV file to save the predictions
