how to detect corrupted file

Using Windows 7.

I could not get wildcards to work in exiv2.
The manual says  "$ exiv2 *.jpg Prints a summary of the Exif information 
for all JPEG files in the directory."
But that gives me "*.jpg: Failed to open the file".

Also, while fiddling with this, the length of exiv2.exe went to 0.  
Maybe the program got tired of my fiddling, or my computer is about to
