We will be officially closing Yahoo! Briefcase on March 30, 2009. Until then, we are offering you the opportunity to download your files back to your computer. You will need to take action before we close, after which any files remaining on Yahoo! Briefcase will be deleted and no longer accessible.So people if you also have anything in your Yahoo Briefcase then better back it up. Else you might just loose you data. Oh yes, the hard part, downloading the data. You have to do it all manually. You've to download each and every of the files one by one. There is no function to download it all at once or to download the whole folder itself. So better start downloading.
I have learnt my lesson the hard way when Yahoo had previously closed its services Yahoo Photos. I'd been a lazy guy by not backing up my data, and so all was lost. Not this time ;)
