I collected data and now I have a large Inquisit Data File (.iqdat). Then I collected some more data in a separate iqdat file. I wanted to combine the two files but I could not find a 'merge' function. I then tried to do it manually, but I found I could do only a single 'Add Row Below' at a time. Is there a more efficient way to either combine data files, or add multiple rows at a time? Thanks!
