In Coldfusion, I am trying to retain the value of a input type=file (for uploading).  When validating my form, all entered values are returned upon submit accept the value for the input type=file field.

How do code to retain value enter or browsed by user or the input type='file' field?

<cfparam name="Form.FileToUpload" default="">
...
<cfif Len(Trim(Form.FileToUpload)) EQ 0>
  <cfset strError = strError & "<li type='square'>Enter or browse for Image to Upload.<br>">
</cfif>
...
<form name="entryForm" id="entryForm" action="entrypublic.cfm" method="post"  enctype="multipart/form-data">
...
<input type="file" name="Form.FileToUpload" value="#HTMLEditFormat(Form.FileToUpload)#" size="35" class="smalltext" tabindex="3" />
...
<input type="hidden" name="submitted" value="yes">
</form>

you can't.
not in cf or any other language - you can't pre-populate an input of type="file". this is a security feature of current HTML standard.

if you submit your form to ANOTHER page that does validation, and on that page tell user to press their browser's back button if there are errors, then when they do press the 'back' button, they will return to the from page, and they [usually] will still have all the info they have selected/typed in previously in the form, including their selection in the FILE input.

but you can't pre-populate a blank FILE input field.

if you are using CFFORM tag and your form submits to itself, you can try specifying preserveData="yes" to make the form display submitted values instead of default values. i an not sure if this works with <cfinput type="file">, though...
