    How to recover a corrupted excel file ?


    We have a file server with windows 2003 sharing some folders, since the last lost of energy the server restarted but we have noticed that some excel files are now corrupted, we got the following message:

    "Excel cannot open the file myfile.xls because the file format or file extension is not valid"

    We have tried to open and repair the file, but always appears an empty file.

    Also, We tried "Excel repair toolbox" application but this tool indicates the following:

    "All bytes in the file myfile.xls are equal zero. Program can not do anything with an empty file"

    Any ideas?

    It appears you have a major file system corruption. This is not an Excel question but a Windows recovery issue. You may need to use utilities such as CHKDSK or similar to see whether it can rebuild the file system. Then, you still may need to recover these specific files from backup. I wouldn't trust anything on that server until this is all done.

    Oh, and get a proper battery backup in place and make sure to use its usb connection so Windows knows to shut itself down safely before the battery is dead.
