That's not correct, you can also monitor changes to a file.

>>>Hi all,

>>>I'm trying to figure out how to detect an update in a text file. I want to monitor updates to a log file from a 3rd party application. I looked at the VFP 9 sample and tweaked it to point at a specific file easily enough, but it only reports file deletion/creation, not updates to the file. Does anyone know how to intercept a file update?
