Filemail Desktop has the option to automatically download all received files to your computer/server. That way you don't need to do this yourself and wait for downloads to finish.
You can specify how the files should be organized (in folders etc.) in order to keep perfect track of everything.
File integrity is guaranteed by downloading files in chunks that have a hash signature.
This feature is often used by print shops, post production companies and others that receives big files on a daily basis.
