downloading files from SQL Server

Using Coldfusion 8 on windows platform with SQL Server 2008 Express.
I have a table that's holds files converted to binary.
When it came time to download I used this:

<cfheader name="content-disposition" value="attachment; filename=#getFile.name#">
<cfcontent variable="#getfile.Contents#">

... Which did everything I needed it to do, invoked a save as dialog box or open file.
Worked perfectly... in Firefox.

I've read this has issues in IE and yep! sure does.

So how can I get my file(s) back??

I shifted to this for the sake of IE knowing I could check the browser and IF it's IE do this:

<cffile action="write"
      file="C:\temp\#getFile.name#"
      output="#getFile.Contents#">

Which works perfectly... if you're saving to the server and not allowing the user to save to their drives, which is what I need.

To that I ask for help!

TIA

Don't you need to use ToBase64() to convert it from Binary before doing cfcontent?

Normally hold the attachments externally, but in SQL 2008 can also hold as filstream - how have you stored them in 2008 ?

as an external file, this normally works :

<cfheader name="Content-Disposition" value="attachment; filename=#GetFile.FileName#">         or might try:   value="inline;
<cfcontent type='application/unknown' file='#RootDirectory#\#GetFile.FileName#'>                        the application/unknown normally invokes the save as...

@ Mark wills:
I converted to binary and stored them in a column of  image datatype. This seems to be working well and when tested  using Firefox and the CFcontent it converts back without using ToBase64() (responding to duncancumming).
OK got it to work: seems 'application/unknown' did the trick, but for the sake of discussion i'm including my code below.
Many thanks!

<cfheader name="content-disposition" value="attachment; filename=#getFile.name#"> 
<cfcontent variable="#getfile.Contents#"> 
<cfcontent type='application/unknown' file='#getfile.Contents#'>
