how to read and edit a file with .work extension

I have been using Pollard's kangaroo for SECPK1 and I'm wondering on how to edit the files with .work extension. I googled it and it said I can use Bibble 5 or Coral AfterShot Pro but I cannot open it using these programs so is there a way to open this file and edit it?? Even notepad++ can't read this file!

Get a trial version of Ultra Edit (ultraedit.com) and open the file.

It may open as in HEX mode. If not and if you cannot make sense of the file, use the Edit tab in Ultra Edit and select HEX mode (or press Ctrl-H to invoke HEX mode).

HEX mode will show recognizable characters / words on the right.

This method will allow you to open the file and then, possibly make sense of it.
