<cfif not isDefined("form.file")>
		<form action="##" method="post" name="test" id="test" enctype="multipart/form-data" class="test">
      				<label for="file" class="label_medium">Upload file</label>
	  			<input type="file" name="file" accept="application/">
	  			<input name="submit" type="submit" value="Submit" class="button" />

<cffile action="upload" filefield="Form.file" destination="#uploadFolder#" nameconflict="makeunique" accept="application/" strict="true" >
<cfif cffile.fileWasSaved is "yes">
	<cfoutput>File saved</cfoutput>
	<cfdump var="#cffile#">
	<cfoutput>File NOT saved</cfoutput>
	<cfdump var="#cffile#">
<cfcatch type="any">
	<cfoutput>Error: #cfcatch.message#</cfoutput>
	<cfdump var="#cfcatch#">


Actual Result:

The MIME type or the Extension of the uploaded file application/msword was not accepted by the server

On CF10 with latest update, the Mime type for excel document is recognised properly as "application/". Please try with latest update and let us know about this. Thanks.

OK attached is an xls file that is being reported as EXTENSION: doc; MIMETYPE: application/vnd.msword; TYPENAME: Microsoft Office Word 97-2003 Document Please do not use this file for any purpose apart from testing - although I have removed any personal info, it still contains some private data.
