What is the best way to store 100 of thousands of .jiff files (<3 MB each) to be used (creating and retreiving) in .net c# new application using oracle 10g db.

We will also need to migrate existing files working with old VB application (with sqlserver) to .net c# application (using oracle 10g)

SO the next question will be to: what is the best way to migrate these files into new db/system

Please advice.
Thanks
