I need to truncate off the extension after uploading a file to a sftp site.

Currently we have orders that are named something.edi.tmp

After they have successfully been uploaded to the sftp site we need the filename to be something.edi

Previously we have used winscp and were able to truncate the tmp extension by renaming all "*.tmp" files to "*." Using this same method in Visual Cron results in an error.

What is the best method for truncating extensions in the sftp rename file task?

Thanks!
