Its not THAT oldhat Napho some of us have been using wrapping for ages and STILL are, its a good way to keep different categories of files separate.
The version on your link seems to be a tidied up version of the original 3.00beta release E which works fine once you get used to its slightly strange habits.
For simple decode of Wrapster filesI reccommend the very small Drag & Drop program which appears often on the shares of folk which is known as V082.exe, its so simple to useand creates the unwrapped file in the same path as the source file.
Wrapster is NOT dead, and it DOES work via Blubster provided you don't use the name "Wrapster" in the file name, which unfortunately breaks the accepted proceduresin the Wrapster help document.
Snark.
