Creating batch file for sftp - do not want to send empty files

I am creating a batch file to sftp files to another server. Sometimes the application that creates the files will create empty files. I do not want to send these, but have not found a way to exclude them.
Any guidance would be great.

Use a file mask with a size constraint

Thank you, Worked perfect... saved me a lot of time
