What is a Reason ReFill?

A Reason ReFill is a kind of component package for Reason that can contain patches, samples, REX files and Song files. On your computer, ReFills appear as large files with the extension ".rfl". Storing audio samples in a Refill will significantly reduce the size of the files, with no loss of audio quality. The advantages of ReFills are obvious; third party manufacturers can produce downloadable sample collections for Reason for example, and it simplifies exchanging samples in general. Samples (Wave and AIFF files) are compressed to about half their original file size when stored in ReFills. With ReFill Packer, you can "pack" patches, samples, Song files etc., into one self-contained file. In Reason, you can use the browser to list and access the embedded sounds and other components within the ReFills. just as if the ReFills were folders on your hard disk.
