How do I list files in a Slack workspace?

Short answer: You can list files in Slack by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Slack List Files action to a workflow, map its 4 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

FAQ

Questions about List Files.

What does the List Files action do in Slack?

Lists files in the workspace, optionally filtered by user, channel, or type. Used for audit, DLP scans, or storage cleanup.

What inputs does List Files require?

List Files has no required inputs. Sensible defaults are applied if you leave fields blank.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if Slack returns an error?

The run history shows the failed step with its input and the error message Slack returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.

Does List Files support batch operations?

Run List Files inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within Slack's rate limits.
