how do i convert qpw files
I guess you have tryed to open it with LibreOffice, que puede abrir algunos tipos de fichero de QuattroPro.
Having been a long-time user of QuattroPro, the only way I found to transfer data was to go back to an old Windows computer, start my old QP program, and export the data as csv files. Then I could transfer that to LO Calc. Of course, all formatting and graphics were lost, including the little bugs in QP that drove me away from it, but at least I still had the original data. I hope you can find an easier way.
