List Files

KNIME Base Nodes version 4.2.2.v202009011342 by KNIME AG, Zurich, Switzerland

This node creates a list with the locations and URLs of the files contained in one or more given folders (content of sub folders can be listed as well). It is possible to apply a filter on the files, so that only the files of interests are included in the resulting list. There are 3 filters available: file extension(s), wildcard pattern or regular expression.
Note that if remote locations are listed, e.g. if the workflow is running on a KNIME Server, then the location column will be empty for files living in the KNIME Server repository. Only URLs are returned in this case.


Select the folders to be scanned. Also KNIME-URLs like "knime://knime.workflow/" are accepted.
Specifies the filter to be applied:
  • none: all files will be included
  • regular expression: only the files matching the regular expression will be included.
  • wildcard pattern: only the files matching the wildcard pattern will be included.
  • extension(s): only the files with the right extension will be included.
Extensions / expression:
Define the file extension(s), a wildcard pattern or a regular expression for the filter. For multiple extensions ";" acts as the separator. This option is ignored if no filter is selected.
Include sub folders:
If enabled the content of the sub folders will be included as well. If disabled sub folders will be ignored.
case sensitive:
If checked the filter is case sensitive.
