Local File Browser Configuration

Allows selecting a local file and exposing it using a flow variable. Variable output representing the file path as variable. In case an absolute file path is selected the node will populate three variables: one representing the path, one representing the URL and one representing the URL as a path variable. If a URL is selected as default file only the URL variable and the URL(path) variable are defined.

Options

Label: A descriptive label that will be shown in the dialog.
Description: Some lines of description that will be shown for instance in the node description of the component exposing a dialog.
Parameter Name: Parameter identifier for external parameterization (e.g. batch execution). This will also be the name of the exported flow variable.
Valid File Extensions: A list of file extensions that is used as filter in the file browser (not only the one in the "Default File" option but also in a remote file browser), e.g. ".csv,.csv.gz" will filter for files ending with ".csv" or ".csv.gz". Leave empty to accept any file.
Default File: The file that will be used during design time, i.e. when no file is provided by a component dialog.
It is possible to enter a URL here. This can be useful if a default file is to be addressed with the knime:// protocol (e.g. knime://knime.workflow/../data/file.csv) or if the file is present on a remote server.
Timeout: The time in seconds after which the connection times out. The timeout is used when testing the existence of default files. The default is set to 1 second and should be sufficient in most cases.
