Parameters

Parameter

Description

absolute_path

An absolute path

Usage

To access a file on a remote system, the account (for Windows) or user (for UNIX and Linux) that is running ColdFusion must have permission to access the file, directory, and remote system. For example, if you run ColdFusion in the Server Configuration as a Windows service, by default it runs under the local system account, which does not have sufficient privileges to access remote systems. You can change this, however, on the Log On page of the Services Properties dialog box.

Example

<h3>FileExists Example</h3>

<cfset thisPath = ExpandPath("*.*")>
<cfset thisDirectory = GetDirectoryFromPath(thisPath)>
<cfoutput>
The current directory is: #GetDirectoryFromPath(thisPath)#
<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 filename, #GetFileFromPath("#thisPath#/#yourfile#")#</p>
    <cfelse>
