No reliable information is available about the vendor, purpose, contents, or software that created a .wk_ file.
Because the format is unidentified, its current status and platform availability cannot be established from the extension alone.
There is no confirmed program for opening a .wk_ file. Identify the application that created or supplied it before trying to open it.
A .wk_ file cannot be converted reliably until its underlying format and creating application are known.
After identifying those, use that application's native export or save-as function, if available.
