With the current Directory Watch capability, a trigger message is fired for every file change that occurs in the watched directory. This is fine when a workbench is required to process each file change.
In the scenario where multiple files are copied into the directory that you want to process all at once (e.g. copy in multiple mid/mif files to be converted into one file geodatabase), a trigger is fired for each file, where you would ideally want one trigger message to say "this directory content has changed".
I would like to see an option on the directory watch configuration to allow either one trigger per file change (i.e. the current situation) or one trigger per directory change (i.e. where one or more files have been changed/created). This will then allow the associated workbench to be run once to process all files in the directory.
