Hi - I'm struggling to find the dialogue box for the wildcard union of .csv files that others have referred to previously. Is this feature still supported in Tableau 10? I saw this in another post Wildcard Union in Tableau 10.0 – Prisoft Technology and have also asked for help there.
When I create the connection to one of the .csv files and then click on the "new union" button, I only get the option to add the files in manually rather than using a wildcard. I get the same for excel files as a data source.
Bit stuck on where I'm going wrong - can anyone help?!
