# Amazon S3 - New file slice trigger

The New file slice trigger monitors when a new file is uploaded to a selected bucket or folder in Amazon S3. This trigger splits the uploaded file into slices of a specified size and creates a job for each individual slice.

Use this trigger to handle large S3 files by breaking them into smaller pieces. Otherwise, use the New file trigger to process the complete file. Use the Download file contents action to retrieve the content of each slice.
