Path to URI

This node generates a URI for each path in a path column. The supported URIs formats are specific to each file system. The URI format to use can be configured in the node dialog. Examples for URI formats are:

file:// URLs (supported by the "Local file system").
presigned https:// URLs (supported by the "Amazon S3 Connector").
knime:// URLs (supported by the "Mountpoint" and "Relative to" file systems).

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.

Options

Column containing the Paths to the files/folders for which to generates URIs.

Fail if file/folder does not exist

If selected, each Path in the input column will be checked for its existence and the node will fail, if the Path does not exist. If not selected, this check will not be performed, but the node might nevertheless if the selecte URI format requires the Path to exist.

Fail on missing values

If selected the node will fail if the selected column contains missing values.
