Thanks for sharing your experience, Magdalena! 
I’m not surprised there were some hiccups—both the software creating the export, and the one importing the data needs to be able to work well with the format for things to go smoothly. I expect the success of RSMF will ultimately depend on how well the specification is written and industry adoption.
I’m happy to see Relativity’s effort. Without a data exchange specification, complex data remains in the silo of the application that captured and/or parsed it. To get the data out of Physical Analyzer or UFED Reader and incorporate it into the mainstream review workflow is very valuable.
