I have several excel files stored on a 16gb usb stick. I use these files from the same computer daily, I have tried to open several files today in Excel 2007. It gives me the following error:

"Excel cannot open the file '(filename)'.xlsx' because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file."
I tried ctrl shift I and got the code 101786, if i click yes the page then opens text import wizard which says my my data is delimited.

I have tried:
Opening in 2003 - the same prob,
I have changed the file names to .xls - still doesnt work

I've tried the "Open and Repair" option of Excel, but to no avail.
I tried copying it with no luck.
I tried 3 different computers...nothing!
I have made duplicates emailed etc but nothing works.

I AM BASICALLY LEFT WITH A ABLANK SPREADSHEET - ALL THAT HAPPENS IS THE TAB NAME IS CHANGED TO THE FILE NAME THE REST IS BLANK!

Can someone please help me out, I cant understand how this has all of a sudden happened - I use these files on a regular basis. I have so much work stored that i cant access! these are really important work files,

I am no expert so a reply in simple terms would be really appreciated

Why does 9 mean SUM in SUBTOTAL?
It is because Sum is the 9th alphabetically in Average, Count, CountA, Max, Min, Product, StDev.S, StDev.P, Sum, VAR.S, VAR.P.
