CFFILE Holding File Locks

Question

I have a CF page that reads some tab-delimited text files for
processing. After it reads a file it then calls a CF page to move
the file to a new location. It moves the file, but it does not
delete the old version -- and a filesystem delete on the file fails
-- it appears as if the CF server has the file locked. If I shut
down the server and restart it, it clears the lock.
<cfif #url.vendor# is "LOWES">
<cflock timeout="10" scope="server" throwOnTimeout="no"
type="exclusive">
<cffile action="move"
source="c:\edifiles\export\#url.fileno#"
destination="c:\edifiles\export\done\lowes\#url.fileno#">
</cflock>
</cfif>

Answer 1

Generally when manipulating files you used a named
<cflock> instead of a scope like so:
<cflock name="#Variables.myFileName#" timeout="5"
type="exclusive">
In your code in the second example I'm not sure about the
function of the loop at all... I guess you are trying to delay to
make sure the copy operation completes before deleting. But looping
from 1 to 10 is arbitrary and depending on other concurrent
processes, server speed, RAM, etc. and so basically it is
unreliable.
