Step Details
Introduced in Version	4.0.0

Location	File Management

The Load and Delete File step loads a file during runtime and removes the file locally. The full path to the file must be provided as input. Once the step completes, the file will be deleted from the file storage and exist only in memory. If only the file name is provided as an input, the step will limit searching for the file in the Decisions directory.
