    File Watcher Usage

    The purpose of the File Watcher functionality is to allow the dynamic execution of a Flow through the monitoring of a directory/directories. If a valid file is added to a watched directory Euclid Studio will call the specified Flow to process the file. This makes it very easy to integrate with systems that produce flat files intented for consumption.

    File Watcher Location

    File Watcher settings can be found under the Execute -> File Watcher... dropdown menu on the Euclid Studio toolbar.
