Yahoo Briefcase, an online storage service, will be closing down at the end of the month, the company has announced.
An email to users of Briefcase informed them that the service would be shut on 30 March and that they should upload files back to their computers.
"You need to take action before we close, after which any files remaining on Yahoo Briefcase will be deleted and no longer accessible," the email reads.
Yahoo Briefcase also offers a paid-for Premium service, which will also be shut. Yahoo promised refunds for affected customers.
Yahoo said in a statement: "Yahoo Briefcase is being discontinued because usage has been significantly declining over the years as users outgrew the need for Yahoo Briefcase and turned to offerings with much more storage and enhanced sharing capabilities, such as Yahoo! Mail and Flickr.
"Discontinuing the service will allow us to focus our efforts on more broadly-used products, in line with our commitment to deliver the best possible user experience," the statement continued.
AOL's Xdrive, another online storage service, was shut down in January.
