I'm new using SSIS.But as i said at topic,had many success tests for these kind of things :
flat file to db or opposite db to flat file.For this title I've made
text to db,db to text,multi text to db,multi csv to db,
rename and move file from one folder to another (using loop container or file task system),
I haven't done exporting many text or csv from a db table.
For excel I searched many sites but usually they're not constructive for people like me.
There was a topic " delete excel file using ssis" something like that.
I've succeed this one,really easy if you think about it for a few time.
Now,I wanna to share these experiences if you want.
