It's also handy for file ops as well. Here's an example of a
recursive delete for CFMX6 since it doesn't support the
'recurse="true"' attribute like CFMX7 (the other functions it
references are in a cf6.cfc that I use):
<cffunction name="deleteDirectory" access="public"
returntype="boolean" hint="I delete a directory by looping through
the contents and deleting the files individually. I am a substitute
for CFMX7's recurse option.">
<cfargument name="directoryVar" required="true" type="string">
<cfset var directoryDeleted = false/>
<cfset var files = "" />
<cfset var folders = ""/>
<cfset var folderQ = "" />
<cfset var directoryList =""/>
<cfset var filesDeleted = false />
<cfif directoryExists(directoryVar)>
<cfdirectory action="list" directory="#directoryVar#"
name="directoryList" mode="777" />
<!--- Get Files to delete and Delete them --->
<cfset files = selectFiles(directoryList) />
<cfset filesDeleted = deleteFiles(files) />
<!--- Get Folders to process --->
<cfset folders = selectFolders(directoryList)>
<cfif folders.recordCount>
<!--- If more folders, rinse and repeat --->
<cfloop query="folders">
<cfset deleted = deleteDirectory(folders.directory & "/" &
folders.name) />
</cfloop>
</cfif>
<cfdirectory action="delete" directory="#directoryVar#" mode="777" />
<cfset directoryDeleted = true/>
</cfif>
<cfreturn directoryDeleted/>
</cffunction>
