Minimum Mule Version



  • The parameters Updated in the last, Not updated in the last and Time unit are added to the File Matcher, which enables you to have a List or Listener operation that filters files based on whether or not they have been updated in the specified time unit.

  • Adds the option to configure FTP Remote Verification.

  • The Time between size check setting prevents the connector from processing files while they are being written.

Fixed Issues

  • Fixed the issue where the read operation was taking more than one connection to read the file content.

  • Fixed a bug that made the read operation fail for certain FTPS servers.

  • Fixed a bug that caused the connector’s listener to skip a file due to a race condition. This happened when the polling frequency of the listener was low, the autodelete flag was true, there was a burst of files to process, and the processing of each file took longer than the polling frequency.

  • Changed log level so that when failing to log out a connection the stack trace is not logged at WARN level.

  • Fixed a regression that affected the use of ftps:listener without specifying a directory.

  • Fixed bug that made the connector get stuck while reading files from a remote server, degrading performance.
