[PHP-WIN] $_FILES, backslashes, input=file and IE 6

[BOb Pardoe]

I have a problem, I am accepting a file type input in IE6. The file that I want to 
upload is shown as 
   
    C:\dir1\dir2\File.ext

Posting this page to the next one, where I try to do     

    $_FILES["filename"]["name"]
All I get is 

    File.ext

This is because of the back slashes. If I change them to forward slashes it all works 
fine.

I have tried to change the \ to / using JavaScript, but as a file type input it is 
read only from the JavaScript perspective.

Has anyone solved this problem ?

If so how

Thanks
