Save File Locally

StreamableVernalis custom KNIME nodes package version 1.12.0.v201708101336 by Vernalis (R&D), UK

This node saves a copy of the text files held in a table column to filepaths held in a second column.
A rudimentary attempt is made to validate the filepaths - which must be complete paths, e.g. C:\Temp\myfile.txt If the full folder path does not exist, an attempt is made to create it.
The returned column will contain a missing value if either of the input columns is a missing value, 'true' if the file was successfully written, and 'false' if it was not written (i.e. because overwrite was set to off, and the file existed, or because the directory could not be created or was not a valid path)
This node can be used to create txt files, or save pdb, mol, mol2 files etc. by providing an appropriate filepath and extension.
