Solved Error message opening excel files. Cannot open files.

September 8, 2014 at 06:19:37
Specs: Windows 64
I have some word and excel files that give me an error when I try to open them. The error reads " Cannot open because file extension is not valid. Verify that the file has not been corrupted and file extension matches format of file." I have gotten this on several of my excel files and a word file. What is causing these and what do I need to do?

Makes me think they became corrupted on transfer to the flash drive. If they are still available on the hard drive of the computer they came from, do those still open (as apposed to the flash drive copies)?

See if THX 1138 (#2) pops back in relation to his question - last line.

Always pop back and let us know the outcome - thanks

Is there any difference between the file extensions on the files that do open and the ones that do not - for both Excel and Word?

What version of Word & Excel were they created on and what version are they trying to be read on? Newer versions of those files can't be read on older versions of the software.

Are these on the same computer or transferred on a flash drive from one computer to another?

There is no difference between the file extensions on the files that do open and the ones that do not. I created these on different computers and tranferred on a flash drive from one computer to another. I do have a newer version on one, but the weird thing is I still cannot open them on the computer I created the file on.

I only have these files on my flash drive. That makes sense that they became corrupted on transfer to flash drive. Would that mean there is a problem with my flash drive? Is there a way to make sure this doesn't happen when saving? I hope that is the extent of the problem and that I don't have more serious problems.

Flash drives don't last forever so it could have died - you could try formatting it (which loses all the data) but even if it works again it is hard to trust it after this sort of problem.

Best way for the future is to transfer them and check them all out on the new computer. That way if anything goes wrong you have two possible places to find them (the computer and the flash drive). Flash drives are not ideal for backup - an external hard disk is best or even CD/DVD-R.
