• Click again on the "forRules" link in the breadcrumb to load the folder details

• Click on "Manage Rules"

• Click on "Create Rules"

• Enter a name for the rule ie "test rule", under "If all criteria are met" select "Name" and "Equals" value "sample.txt", this will ensure the rule only runs for the sample.txt file

The exploded folder contains one file "backuplog.txt" and two folders "CustomFolder" and "OotbFolder"

[Observed Behaviour]

The exploded folder contais one file "backuplog.txt" and the folder "OotbFolder".

[Analysis to date]

The API seems to be skipping custom type folders. The problematic line seems to be https://github.com/Alfresco/alfresco-repository/blob/master/src/main/java/org/alfresco/repo/download/ZipDownloadExporter.java#L137. This has been reported in the past and confirmed to be a bug but it has not been fixed:
