Creates or adds a file extension query to an existing file query filter.

When you wire this function to Query Files, the results only contain files that have a name property that matches the file extension query. If you provide multiple extension queries, the last extension query overrides all preceding ones.

connector_pane_image
datatype_icon

operator

Criteria for how to filter files on the server.

Default: equal

datatype_icon

filter in

Query or queries you want to use find matching files on the server.

Default: new filter

datatype_icon

extension

File extension to add.

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

filter out

Updated query or queries to find matching files on the server.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
