# Amazon S3 action - Download file
This action downloads contents of a file in Amazon S3. File contents can be used in subsequent steps of the recipe to upload the file into other applications.
This action uses streaming mechanism and can support large file. However, the maximum file size you can download depends on how long the download takes. It is limit to Workato's job runtime limit (5400 seconds). Consider enabling Amazon S3 transfer acceleration (opens new window) to speed up the download.
