Thanks!I am afraid we already did this - we export values only, with no decimals and only 2 values per second (the original export format is 16 values per second).The problem is that in Europe we use 24 hours recording...Each manufacturer has its own way of storing data, some in SQL, others in Oracle. The file is then exported in XML following a common export format to allow other physicians to see the tracings and discuss the diagnosis.i suppose WinZip is the best current option though I would rather have an easier method for my "non-computer litterate" users. Any idea welcome ...Thanks again 4 your help.
