Can I read multiple files using filters in Tableau. I don't want union my files as it makes the file very large. Instead of large file, I want multiple small files which will be called according to choice of filter.
So you are saying switch the data source based on a filter? - I don't believe you can.
I know you can filter across different data sources in Tab10: As requested, you can filter across data sources in Tableau 10 | Tableau Software
How many records would your data source be if you union-ed them? Tableau is pretty speedy- especially if it's on an Extract.
