Hi all

Not sure if this is the correct forum for this sort of thing?

I work with some instruments that need to be updated with reference data from time to time. The instrument is controlled from a Windows 7 PC and the reference data comes from the overseas manufacturer in a file in a proprietary format (.qxn). The following link is an example of such a file

I would like to be able to open the file, change some of the data and re-save in the same format so the instrument can be updated with my own data.

Can anyone point me in the right direction of where to start with this? Have tried the obvious newbie things like trying to open with Excel, Word, notepad etc etc with no luck. Is there a program or application that might help me access the data in these files?

Any help appreciated.

Cheers
