OIC - File adapter vs FTP adapter

 File Adapter

• The File adapter allows integrating with remote file servers for reading and writing files. You can use the File adapter with connectivity agent in scenarios where it is not possible to open up the FTP server to the Integration cloud.
• The remote file is read using the File adapter trigger. Writing to remote files can be configured using the file adapter as invoke.

FTP Adapter

• The FTP Adapter enables the integration of FTP servers (FTP/sFTP protocols) to integration cloud. It does not require a connectivity agent and the remote FTP server should be made accessible from the Integration cloud.
• FTP Adapter cannot be used as a trigger but you can use Scheduled orchestration and add FTP as invoke for modeling trigger type integrations.
