Advice required with lost data on iPad
Hello, I'm looking for some advice regarding the iPad and Office 2HD. It's for a friend who is working offshore, so is unable to get online.
He has been working on a word document using Office 2HD on the iPad for the last 7 days. He's been saving his work at the end of each day, then opening it the following day to continue writing.
He opened the file today, wrote a few pages, and then saved it as normal. He then fell asleep with the iPad in hand and with the file still open, and woke up to a blank page. He pressed undo several times but nothing happened. He powered off the iPad and turned it back on, opened the file but it was still a blank page. He's checked to see if it has saved anywhere else under any other name, but it hasn't.
Is there any possibility of recovering the lost work?
Just to be clear, the file itself is still there, but it is now just a blank word document.
I'd really appreciate any help with this. It's over 100 hours’ worth of work.
