Does anybody know of a file recovery programme. I have a Publisher document and an Excel spreadsheet which have, some reason, become corrupted and impossible to open. I have been working with both files for a very long time and, whilst I will be able to recreate the Publisher file because it is the chapter of a book, it will take a lot of time and effort. The data on the spreadsheet will be impossible to fully recover. I would be grateful for any advice you can give.
