Dynamically Create Text File As Destination From Sql Script In SSIS

I have a select Script as follows:



SELECT c.ABC AS 'ABC'

, a.Qty AS 'Quantity_Recived'

, b.PC AS 'PC'

, b.PC AS 'PC'

, 'I' AS 'Flag'

FROM TNRInventory.dbo.tInventoryAlloc AS a

LEFT OUTER JOIN vwInventoryAllocMapping AS vwMap ON a.TNRAllocTypeID = vwMap.TNRInventoryAllocID

LEFT OUTER JOIN ABC.dbo.ZREFRESHTAB AS b ON a.DispenserID = b.Asset

LEFT OUTER JOIN ABC.dbo.TableJoinKey AS c ON a.TitleID = c.TITLE_ID

WHERE (vwMap.DataSourceID = 3) and vwMap.[DataSourceAllocName] = 'I'

group by c.SKU_NO , vwMap.[DataSourceAllocName],a.Qty , b.Profit_Center

order by c.SKU_NO,vwMap.[DataSourceAllocName]

GO



i have to send the result of aforesaid script in batch of 300 records per file (tab delimited text file)
now the file name must be dynamically created as each file will contain 300 records.



I have found some document related to same issue on this url

but still there is a catch.



Can any one guide/suggest me better way to do the aforesaid.



Thanks
