How to undo 'exclude from project' in Visu

Question

Undo VS 'Exclude from project'?

I mistakenly chose the Exclude From Project menu item thinking I could choose what to exclude but it excluded the currently opened file.

I did not notice what file that was and there is no undo enabled.

How can I undo this operation? How can I detect what file was excluded? Is there some kind of log file?

Answer 1

Choose "Add > Existing Item..." then add the files you have excluded
