ColdFusion 8: Added this function.





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.


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.


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.


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 Working with in-memory files in the Developing ColdFusion Applications.


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:

<h3>FileCopy Example</h3>
<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>
FileCopy(#sourcefile#, #destinationfile#);
<cfoutput>Copied: #sourcefile# <br>
To: #destinationfile#</cfoutput><br>
<cfoutput>The source file does not exist.</cfoutput><br>
