Remove unused file from UiPath (Local machine)

Hi ,

I have a situation from production environment, I found that when orchestrator has triggered on unattended robot to run process, it consumed disk space on C: drive. And it consumed more for run in the next next process. So I faces with the issue of not enough space on unattended robot.
How can I deal with it? Please suggest. Or Can I remove some trash file which generated by orchestrator in unattended robot local disk ?
