File Handling

The file handling plug-in can execute file operations within KNIME workflows.

Two new data types get handled. The URI Cell holds a reference to a file. The Binary Object Cell contains a files binary representation directly in the table. The file handling plug-in contains converter nodes for these two types. The remote nodes handle files that are accessible over a remote protocol like SFTP. One of the main features is the download and upload of files.

Through the connection nodes, the login to remote locations can be specified. There are zip and unzip nodes to handle zip files. Properties of a file can be found out by using the file meta info node and the find MIME-Type node finds the correspondent MIME-Type to the extension of a file. Additional MIME-Types can be added via extension point.
