By using GetFileInfo(path) you can get the size of the file and whether or not read and write permissions are enabled. It will also return the ‘type’, but it’s simply ‘file’ vs ‘folder’, not mime-type.

Example:

<cfset test = GetFileInfo(myFilePath)>
<cfdump var="#test#">

Example in use:

<!--- Check if file exists and is not readable --->
<cfif fileExists(myFilePath) AND NOT GetFileInfo(myFilePath).canRead>
    <!--- then Update in DB with file path and some Status --->
</cfif>

If your requirement assumes that you’re validating the file type and not just the ability to open the file, then you will need to update your question to list the file types you must test for so that we can help you out with that part. Some types can be validated by Coldfusion, others may require some Java.
