Run the utility Chkdsk does not solve my problem. What should I do next?

I'm running an Excel 2007 worksheet by using the extensions both on a zip drive .xls and .xlsx.  I tried to open the two files on my PC at work, using Windows XP SP2.  I received the error message that "Excel cannot open the file because the file format or file extension is not valid.  Check that the file has not been damaged and that the file extension matches the format of the file. "I ran the utility twice using the following process: desktop > click the drive where the file > properties > tools > check now > will search for and attempt recovery of bad sectors.  When the disk check process is completed, a dialog box appears that reads "check disk is over."  No exit code was given at the end of each race.

What should I do now?  BTW, I ran the Recovery Toolbox for Excel.  Read message "the file or directory is corrupted and unreadable.  Please run the Chkdsk utility."

Thank you

Yogi,

You should always start your own thread, even if you think that your problem is exactly 'the same' as the issue raised by the original question.  After all, if you have had exactly the same problem, you should be able to use exactly the same solution and should not be asked.

The data retrieved by chkdsk may or may not be usable.  The simplest data - for example, a plain text file - the more likely a file retrieved will be usable by the appropriate application.  More complex data - such as files created by Excel, Word and Powerpoint - may lack the essential elements of the formatting of the data that can make the unopenable file.

That said, you need to rename a data file retrieved with the extension (3 or 4 characters after the dot) appropriate for the application you want to use with the file.  For example, if you see a file named Dec12Letter.chk, and you know that it is a Word file, rename it to Dec12Letter.doc.

For Excel files, use .xls and Powerpoint, use. ppt.

If you are using Office 2007 or 2010, use 4 letter extensions: docx, xlsx, pptx instead.
