This nodes deletes files and folders listed in a Path column. The node has got an optional input port for a File System connection which can be used to delete files and folders on different file systems. Note that if the node is connected to a file system all paths will be resolved against the connected file system. In case the input column contains a path from a connected file system and no filesystem connection is connected, the node will fail during execution.
This node can access a variety of different file systems. More information about file handling in KNIME can be found in the official File Handling Guide.
