what language is this file writen in? : I have been assigned a task to retrieve information from files that were processed from raw mass spectrophotometry data (file.mzML). 
These files have just ".data" as extension and when I open them, I cannot recognize the language and therefore I cannot load them into R and work on them.

The files with the .data extension are contained in this folder:

    ftp://ftp.pride.ebi.ac.uk/pride/data/archive/2015/11/PXD000299/

Could someone take a look at any of the files.data and tell me the language is in (e.g. F010439)? 

Thank you very much!
