As long as you use a named lock around the file operations, I don't know why
it would cause any issues:
<cflock name="#fullPathToTheFile#" type="exclusive" timeout="30">
<cffile action="doSomething" .../>
</cflock>

Subject: [CFCDev] Re: cffile/cfdirectory within a DAO
so no one has used XML files as a data source within DAO's ?
I just need to confirm that locking for file access (read, write,
delete) is kosher within a cfc and that there's nothing I've missed...
