Cannot delete file:Cannot read from the source file or disk

[Redpost33]

Hi,

I've got a 4gb pen that i use for school work.

I put a file with images in it and i want to delete it now but it keeps coming up with:

'Cannot delete file:Cannot read from the source file or disk '

I have tried various ways to delete it but still i can't.

Can anyone help me?

Thanks
