Although the default chunk size is 15 MB, this size can dynamically change, starting from 5 MB and gradually increasing to the 50 MB maximum, based on factors such as network latency, server response time, and so on.

+  Chunk size is associated with a connection, which means that you can use the same connection for actions that support chunking and then for actions that don't support chunking. In this case, the chunk size for actions that don't support chunking ranges from 5 MB to 50 MB. This table shows which SFTP-SSH actions support chunking:

-  To handle files larger than 15 MB, SFTP-SSH actions can use [message chunking](../logic-apps/logic-apps-handle-large-messages.md). However, the Copy File action supports only 15 MB files because that action doesn't support message chunking. SFTP-SSH triggers don't support chunking. To upload large files, you need both read and write permissions for the root folder on your SFTP server.
