Parameters

Parameter

Description

source

Pathname of the on-disk or in-memory file to copy. If not an absolute path (starting with a drive letter and a colon, or a forward or backward slash), it is relative to the ColdFusion temporary directory, which is returned by the GetTempDirectory function.

destination

Pathname of an on-disk or in-memory directory or file on the web server where the file is copied. If you specify a filename without a directory path, ColdFusion copies it relative to the source directory.

Usage

Use the following syntax to specify an in-memory file or directory, which is not written to disk. In-memory files speed processing of transient data.

ram:///filepath

The filepath can include directories, for example ram:///petStore/images/poodle.jpg. Create the directories in the path before you specify the file. For more information on using in-memory files, see Optimizing transient files in the Developing ColdFusion Applications.

Example

The following example copies the test1.txt file from the c:\testingdir\ directory to the c:\productiondir\ directory in Windows and names the new copy of the file test2.txt:

<cfset sourcefile="c:\testingdir\test1.txt"> 
<cfset destinationfile="c:\productiondir\test2.txt"> 
 
<cfif FileExists(#sourcefile#)> 
    <cfif FileExists(#destinationfile#)> 
        <cfoutput>A copy of #destinationfile# already exists.</cfoutput> 
    <cfelse> 
        <cfscript> 
        FileCopy(#sourcefile#, #destinationfile#); 
        </cfscript> 
        <cfoutput>Copied: #sourcefile# <br> 
            To: #destinationfile#</cfoutput><br> 
    </cfif> 
<cfelse> 
    <cfoutput>The source file does not exist.</cfoutput><br>
