How do I find the size of a directory?
Use the <cfdirectory> tag, and then do a query of queries on the results:
<cfdirectory
directory="c:\cfusionmx"
action="list"
name="cfDir"
recurse="true">
<cfquery dbtype="query" name="dirSize">
select sum(size) as size from cfDir
</cfquery>
<cfset sizeMb = dirSize.size/1000000>
<cfoutput>#numberFormat(sizeMB,",.99")#</cfoutput>
In the example above, the result is modified to return a value in megabytes. Also note the use of recurse="true" in the <cfdirectory> tag. This will return all the files including those beneath the directory specified. If you only want the size of the files in the directory itself, change recurse to false.
