You can change the order of the file formats listed in the Save as type list in the Export dialog by doing the following:
- Navigate to the Surfer installation folder (by default this is C:\Program Files\Golden Software\Surfer <version>). Select the Gsio.ini file, press CTRL+C to copy the file, and then press CTRL+V to paste a copy into the same directory.
- Open a text editor program like Notepad as administrator.
- Click File | Open.
- Select All Files (*.*) from the file type list.
- Navigate to the Surfer installation folder and select the Gsio.ini file.
- Click Open.
- At the bottom of the file, under [ExportFilters], highlight the file format you want to be first, and press CTRL+X to cut it.
- Remove the empty line.
- Click before the first file format and press ENTER to add a new empty line at the beginning of the file formats list.
- Click in that empty line and press CTRL+V to paste the cut file format to the top of the list.
- Copy steps 7-10 as desired to rearrange the file format order (you don't have to add the empty line at the beginning of the list in step 9).
* Be sure not to remove or duplicate any information.
