There is no file types associated to the Rawdata structure : when the content of a Rawdata
variable is written into a file, the content of the file is exactly the content of the
field. There is no header added. Consequently, file of any format can be loaded into a Rawdata variable. If this file contains a header (as most of MegaWave2 file formats), the header will
be loaded into the
data field together with the data themselves.
Of course, there cannot be any conversion format associated to Rawdata.
