<cfset thisPath = ExpandPath("*.*")>

<cfif IsDefined("FORM.yourFile")>
<cfif FORM.yourFile is not "">
<cfset yourFile = FORM.yourFile>
   <cfif FileExists(ExpandPath(yourfile))>
   <p>Your file exists in this directory. You entered
   the correct file name, #GetFileFromPath("#thisPath#/#yourfile#")#

this works fine locally but creates some problems when i try it on the remote server. does fileexist only work for local files?

The account (for Windows) or user (for UNIX and Linux) that is runnig ColdFusion must have permission to access the file, directory and remote system.
For example, if you run ColdFusion MX in the Server Configuration as a Windows service, by default it runs under the local system account, which does not have sufficient rights to access remote systems.
(You can change this in the service properties dialog Log On page.)

on a shared server, I received the following error trying to check for the existence of an image file:

Security: The requested template has been denied access to images\products\thumbs\offi\zumiStool.gif.
The following is the internal exception message: access denied (java.io.FilePermission images\products\thumbs\offi\zumiStool.gif read)

The error occurred in D:\FTP\twojakes\Htdocs\dev.cfm: line 70

68 : <cfoutput QUERY="intro">
69 : <a href="##_#itemoid#">
70 : <cfif FileExists("images/products/thumbs/#image#")>
71 : <img src="images/products/thumbs/#image#" border="0">
72 : <cfelse>

Please try the following:

* Check the ColdFusion documentation to verify that you are using the correct syntax.
* Search the Knowledge Base to find a solution to your problem.

the problem i described was resolved by my hosts tech support:

I believe that the problem is cased by the short path to the file that you are using, please try to use "D:\FTP\twojakes\Htdocs\....\images\products\thumbs\#image#" and let us know the results. Probably, there is no read access allowed to that folder/file?

You know, for examples of these kinds of functions, instead of some convoluted result of a function of a variable for the parameter in the example, it would be *much* more helpful if it would just give a straight forward example with a simple parameter so you can see simple things like "do I need to put the path in quotes or not?"

FileExists(c:\foo\bar.txt) or FileExists("c:\foo\bar.txt") would be MUCH more useful in a reference than the current FileExists(ExpandPath(yourfile))
This is a common problem with the examples.
