Workflows Explained - TrueCommerce/CloudFtpBridge GitHub Wiki
As of v3.0.0, files are no longer staged in processing, failed, or archive directories. Instead, the audit log should be used to track file transfer progress.
v2.7.0 and earlier
When a workflow is executed, the service will first enumerate all files in the source directory (the remote FTP folder for Inbound workflows and the local directory for Outbound workflows). If you've provided a filter expression, the service will ignore any files that do not match the expression (only the file name is used for this test, not the full path). Any files that matched the expression will be moved to the CloudFtpBridge_Processing folder, which is created as a child of the source directory. If a file is copied successfully to the destination, it will be moved from the processing folder to the CloudFtpBridge_Archive folder. Otherwise, it will be moved to CloudFtpBridge_Failed.
If an exception is thrown at any point during a workflow execution, the exception will be logged and the error message will be emailed using the settings provided in the Email Alerts tab (if applicable).
