Re: Open files with custom commands in 12.04
dino99 didn't quite read carefully enough that you are not trying to open a .bin file, but a .fits file.
From Help in the file manager:
- Select a file of the type whose default application you want to change. For example, to change which application is used to open MP3 files, select a .mp3 file.
- Right-click the file and select Properties.
- Select the Open With tab.
- Select the application you want and click Set as default. By default, the file manager only shows applications it knows can handle the file. To look through all the applications on your computer, click Show other applications.
If Other Applications contains an application you sometimes want to use, but don't want to make the default, select that application and click Add. This will add it to Recommended Applications. You will then be able to use this application by right-clicking the file and selecting it from the list.
This changes the default application not just for the selected file, but for all files with the same type.
