If you have QuickBooks 2010 R12 installed, then you can use the AutoRecovery option, but in case that fails, a recovery solution needs to be used. Access the application's page for Recuva on Software Informer and download the application. After it has been downloaded and installed, start it and use the wizard to narrow down the search list by selecting the type of file (choose all in your case), partition, etc. Once it finishes, use the filter field to define the type of files used by Quickbooks. Narrow down the results by typing *.EXTENSION.
