Data that only exists on the hard drive is data that you do not care about losing. There are many programs that 'might' recover the data, most are not free. None will give a guarantee, but before you start at least make a copy of the corrupt file now, so that any extraction of data that you try will not make it worse. Look here for a start. Re: Please help to recover file, file format is not valid Well, it is a common case of corruption and you need not to worry as it can be fixed easily. As like any other file format on Mac Excel files can also get damaged or inaccessible due to several possible reasons.
Hi,
My computer recently crashed (auto shut down). Usually when this happens, when I power up and open excel the next time, there is an option to recover unsaved file during sudden shut down.
But for this latest crash, there is no option for me to recover unsaved file, and it displays a popup box when I double click to open the xls file
The popup box shows:
'myfile.xls:: file format is not valid.' with a 'ok' button.
All my previous work is missing too. The whole file becomes empty like a new workbook.
Is there any way I could recover the file?
Usually where are the recover unsaved files stored? and where are the auto saved stored?
Thanks for all help
(unfortunately, my last backup was done one month ago and some errors in the harddisk stopped the backup schedule from going smoothly.)
