Fix file associations in LibreOffice Calc

Question

How do you fix the file extension associations with LibreOffice Calc? I have a CSV-like file with a *.dsv file extension. Ubuntu has that file type set as a CSV document. When I explicitly try to open it with LibreOffice Calc, LibreOffice insists on opening it in Writer. E.g., I can run the command:

soffice --calc ./mydata.dsv

and LibreOffice will force it to open in Writer rather than Calc. How do I fix this?

Answer 1

• Open Ubuntu's file manager ("Files", i.e., Dolphin, Nautilus, etc.).
• Right-click on a .dsv file and select Properties.
• On the Open With tab, find Calc, and select it.
• Click on Set as default.

If that doesn't work, then you can create a new MIME type, or create a .desktop file to set file association.

N.B. This question pretty much duplicates one in Ask Ubuntu.
