I have been sent what is supposed to an audio file for me to transcribe, but it has a file extension of wma.skf and I've never come across that before. An exhaustive search using Google has got me nowhere fast. Can anyone help please? I've gone back to the client and asked them to send me the file in a different format that my system supports but I would rather have a bit more information rather than just forget it - I might come across this again or be able to help someone else if I have the information myself. Cheers everyone.
