For similar reasons I was looking for a way to check the existence of a file without causing an error message. I came up with this: https://github.com/reduzent/netpd/blob/master/includes/netpd-if-file.pd It uses [readdir] from moocow and [getdir] from ggee. Though quite kludgey, it was the only way I was able to achieve that. If someone knows of a better way (even if it uses an external), please let us know. Roman
