Hi, marc.
You wrote:
"... the file was a simple text capture ..."
By this, do you mean you copied and pasted the text from, say, a Web page to a new document in some text editor?
If so, drag and drop the file on the icon for TextEdit. TextEdit resides in the Macintosh HD > Applications folder.
If the file opens and it contains:
• Styled text, e.g. text in bold, italic, etc., then the extension can be reset to
.rtf for Rich Text Format.
• Plain text, then the extension can be reset to
.txt for plain text format.
Quit TextEdit, then reset the extension:
1. Open the file's Get Info window: Control-click the file and select Get Info from the resulting contextual menu.
2. Click the disclosure triangle next to the "Name & Extension" panel.
3. In the text entry field, change the extension from
.wbn to either
.rtf or
.txt per your test above.
4. If prompted to confirm your intent to change the extension, select the "Use..." chocice.
5. Close (Command-W) the Get Info window.
I can't say why the extension changed: it may have been a typo you made earlier and ignored, some programming error, etc. To rule out the possibility of directory corruption, I suggest you run at Steps 1-3 of the Procedure specified in my
"Resolving Disk, Permission, and Cache Corruption" FAQ.
AFAIK, based on a search of the usual sites providing definitions of file extensions, I've not found any reference to
.wbn.
Good luck!
