Some of my Quattro spreadsheet files are saved as WB3s but many are qpw and I don’t seem to be able to access them. The WP Office I had isn’t compatible with Windows 7, which is why I’m now using Libre Office, but I can’t open these spreadsheets. Help.
LibreOffice can not open qpw files. Your best bet is to get a trial version of the current release of Wordperfect Office, open all your qpw files and save them as ODS (or CSV if they only contain data)
From Quattro, first convert to Lotus 123 format. The formulas are retained. Open in L.O., where you can then save as your native (or xls) file format.
