I have an Excel file in my code directory, which I use for documentation. When I search for text (i.e rt. click on text -> search text -> project) I get an error when it tries to search the .xlsx file. This is annoying, and I made it less annoying by minimizing the error message. Now I hae figured out how to make it entirely go away.
Project -> Properties -> Resource -> Resource filters -> exclude *.xlsx. This makes the spreadsheet disappear from the CCS project file list and it is no longer searched.
