There are cruel situations that happen to most of the people who sits in front of there computer typing an word document for hours together and suddenly everything is lost, maybe due to power loss or your own mistake of not pressing the save button on time. In either of the case, we have a simple solution to fix and to avoid loss of Word files from Microsoft word document.
Go to the Word option (Microsoft Word 2007) from the word menu and navigate to Advanced tab, you will find various unchecked boxes, now check Always create backup copy then Allow background saves that will help you to recover files automatically in the future. The backup of word files are saved with . wbk extension.
So from next time if you’ve unsaved or deleted word file, you can always recover it with the backup copy.
There are two simple ways to get the word file from this technique. You can make a search on your user application data or check the temporary folder.
Open the above address in windows explorer. If you have your operating system installed in other drive apart from C drive then change the extension of the above address. Also replace username with your OS name, you can find lots of temporary unsaved files with this tip.
One more trick I found out is to open your Microsoft word once again after any power loss or system crash. Microsoft word will try to recover the lost data automatically! Hope this helps.
